Don’t relent… He’s 19. I was there, 3000 years ago, and looking back now, I also had shitty thoughts and takes. Don’t budge an inch and keep explaining, with evidence, why he is wrong. He will see it eventually but needs a guiding hand to change his views.

Don’t panic or react much that’s what groypers are after. Just keep calm and deboonking. Groypers these days are are acceleration nihilists. They don’t really believe in anything. Half of the shit he is saying is just for shock value. The other half isn’t far off from the truth when you ignore the hyperbole. When you correct him and he shrugs it off its not because he doesn’t care he is bouncing ideas off you because he respects your opinion. He’s also mining for new ideas to pitch to his online community. The more cutting and extreme your rebuttals the more likely he is to absorb them and use them.

Amazing how applicable 96 year old quotes are:

National and racial chauvinism is a vestige of the misanthropic customs characteristic of the period of cannibalism. Anti-semitism, as an extreme form of racial chauvinism, is the most dangerous vestige of cannibalism.

Anti-semitism is of advantage to the exploiters as a lightning conductor that deflects the blows aimed by the working people at capitalism. Anti-semitism is dangerous for the working people as being a false path that leads them off the right road and lands them in the jungle. Hence Communists, as consistent internationalists, cannot but be irreconcilable, sworn enemies of anti-semitism.

He thinks Nick Fuentes is funny, and likes that he is “one of the only far-right people who doesn’t utterly despise Muslims/Arabs”

This is what happens when you have no materialist understanding of the world around you, or even a humanist one. Seriously, maybe broach other topics to him besides Israel Palestine? Communist theory isn’t downstream from Israel-Palestine

Bring him to a Palestine protest with Jewish Voice for Peace. The best way is to break this misconception is to be active IRL and see Jews fighting for Palestine on the ground, and see how they are ignored.

tell him the shit he’s saying is making netanyahu a very happy boy

Be a bro to him. My lil bro had a short lived “right winger phase”, he was going on the South American manosphere rabbit hole, I started spending more time with him and softly correcting his ‘positions’ never letting go of harmful bullshit but always trying to listening to him and letting him speak his mind. Then college started and he met his new friends (male and female) and now he’s well adjusted (or at least not manosphere-adjusted).

So basically include him in social activities, call bullshit where bullshit should be called, trust him and let the normal socialization hammer down the worst of his positions.

It might help to have antizionist jewish friends interact with him but that is low-key more antisemitic than anyone I’ve encountered offline. Also Fuentes literally thinks muslims shouldn’t have constitutional rights he thinks your brother is subhuman

Might also help to point out how the Zionists benefit from people associating all Jewish people with their genocide. Those kinda accusations are used by Zionists to justify their ethnic cleansing.

As mentioned by this article, to deradicalize extremists, former neo-Nazis use a radical method: empathy.

My advice will be to get help from any organization like this one mentioned in the article. Maybe, they can teach you or show you some resources on how to achieve deradicalization.

Ok this is probably gonna be tough but you will need to put a lot of effort into it. The fact you posted it here already shows that you care a lot about your brother and that is great, that is something that you need to make clear (through action, not simply saying it) so he at least understands your intentions are the best.

So, to start, have you ever talked with him about this bad treatment you did of him in the past at all? I used to take my anger at my brother when we were kids, I won’t list the reasons here for opsec reasons, but it does have to do with me being autistic and the bullying I suffered. I recently talked with my brother about it (we have a good relationship for multiple years now, but the blame still fucked me in the head) and the talk was great and I feel got us a bit closer.

If you don’t think that is something you can do right now, focus on building a better relationship with him first, then touch on the subject.

You can also just explicitly tell him you are deeply concerned about all this right win rhetoric he is spouting and that you are genuinely concerned about him and that you want to help him see different. This will only work if you feel you have the type of relationship were he will take it seriously, so weight in if you want to say that.

edgy humor which is sometimes borderline centrist/center-right

He’s young, it sucks to have someone close with this type of “humor” but it happens, I unfortunately had some pretty bad “humor” at that age too.

I’ll try to tackle a few of the numbered points you mentioned. What I can say beforehand is that logic itself is not gonna convince him, the reason for that is that he arrived at his conclusions with logic, deeply flawed and fucked up logic, but logic nonetheless. Simply trying to win arguments and prove someone’s logic wrong is not a way to convince people, I say that from experience. What I have found to work is to present verifiable facts and to try to make the person you’re talking to come to the same conclusion as you on topics they already have a made up mind. Of course, it is different from person to person and when someone asks you to explicitly explain something, but I think it is good to keep this all in mind.

1. He thinks that in modern times, Jews control western nations including US through the media, banks, legal institutions etc.

The best way to counter this narrative is to ask him to prove it, and then you need to counter the bs he spouts from this with verifiable information/facts. You also need to question him how that works and find flaws in his argument, you need to deconstruct his view and let him come to the conclusion that argument is flawed and wrong. You do need to be very knowledgeable on all this tho, so if needed, study up, specially the arguments he is mostly liked to spout.

2. He knows that Zionists != Jews, but says it doesn’t matter to him at this point

That’s an emotional response and I don’t think you can easily counter this other than by showing him the large footage of pro-Palestinian Jewish people.

3. Despite my best efforts to explain Israel’s role in US imperialism, he still thinks “the middle east wouldnt be as bad” if not for Israel

He’s not wrong, but you need to show him how the existence of Israel is a direct result of the west and the US. Proof like the video of Joe Biden admitting that if Israel didn’t exist, the US would need to create an Israel to further US’ interest in the region is probably a great way of showing him that.

5. He sends me reels of Israeli rabbis saying crazy shit with Havah Nagilah playing in the background

There’s not much you can do here, the evidence of Israelis saying the most heinous shit imaginable is gigantic. Differentiating these Zionists from Jewish people like I talked before with video proof is probably the best thing you can do in this regard.

6. sent me an Amin al-Husseini x Hitler edit (he joked saying how husseini saw the future and wanted to save his people, and that maybe Hitler was right)

Now this is a line he crossed and you need to make that CLEAR. This type of shit cannot pass, you need to tuck at his heartstrings if simply stating it is not enough, you need to show him how bad it is. Show him how Jewish people were not the only ones being target, Romani, Queer people and leftists were too, show him how Nazi Germany was just capitalism incarnate, show him how Zionism helped Nazism until they realized they couldn’t anymore, show him that it is not the Jewish people’s fault. I know it is in Portuguese, but Breno Altman, a Jewish Brasilian Marxist and heavily anti-Zionist talks about it in this video. You should also show China’s and the DPRK stances on Israel and Zionism and other AES and previously Socialist countries stance on that.

8. He thinks Nick Fuentes is funny, and likes that he is “one of the only far-right people who doesn’t utterly despise Muslims/Arabs”

I don’t know much about Fuentes other than that he is a fucking Nazi, so it would probably be a good idea to find material that refutes him and shows how his views are abhorrent.

Also, last, but not least, you need to play by his rules. What I mean is that if he is sending you bullshit fascist edits, then you need to start sending Marxist edits. It doesn’t matter that it might not be perfect, or that it might be slightly wrong, start sending him edits and other Marxist short-form content. I know KazakhMarxist is one good source for that. There’s also other great comrades that do short-form Marxist content like Lady Izdihar (she converted to Islam) and James Rehwald.

Would Hakim’s channel help? Videos of Ghassan Kanafani’s interviews/speeches? Would Lowkey’s or Immortal Technique’s music help? The former’s other videos and interviews? Would Akala’s videos help? Malcolm X?

How about considering usury is unearned income and going down that route to reach anti-capitalism? Or that Zionists learned their fascism from Nazis (and Brits) who in turn learned it from USAmericans (and also Brits again)? That all palestinian resistance on the ground have ultimately concluded that the US is behind the Israelis and not the other way round?

But above all empathy to echo rainpizza. You win with empathy and finding common material interests together; making the case (you may have to discover for yourself what/how and to do that you have to truly understands what he wants) that he benefits within the short term sharing your perspective. Maybe consider day to day challenges and how that fits into the bigger picture of the destructiveness of imperialism and fascism. You have to correctly identify shaitan and his mechanisms or he will forever evade you.
