Here in the Netherlands there is two kinds of antisemitism now - the regular kind which still is terrible and the ‘what Israel calls antisemitism’ which doesn’t hold any meaning anymore. They’ve called everyone anti-semitic by now. The UN, the ICC, many major pilitical parties, jews protesting against genocide, the dutch police after investigating crimes comitted by Israeli citizens. You are right and we should be wary to take Netanyahu’s diluted definition serious, because there still is real antisemitism and if we’re not careful the (in my pov justified) hatred of the Israeli government will transgress to jews who have nothing to do with the genocide of Palestine. And yes, we should similarly rejects Trumps definition of terrorist.
