There’s a clear campaign against the mentally ill with the global rise of fascism. Lots of it shows up in anti homeless rhetoric, but you can see it in the MAHA and anti vaccination movements.
There’s no reason to use the word “r-tarded” to describe someone. As someone who’s worked with the intellectually challenged, it’s an insult to them to compare them with people who are willfully ignorant.
If a group of people are telling me this word was and continues to be used as a dehumanizing slur, that’s enough for me to look into a vocabulary change. More importantly, the very existence of a euphemism treadmill shows that you can’t stop at language change, and that disabled people need to be much more fully accepted in society.
I got a lot of hate in this thread but I agree with you. We need to much more accepting of people in society disabled or just different. A word change makes you feel good but doesn’t actually do anything. A business with a curb should be required to have a ramp also, for wheelchairs. I wish there was a some sort of option for drive-thru for deaf people. A person with autism who gets overly stimulated by people close should be allowed to ask for personal distance.
