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.
I’ve stopped using it as people have pointed out it’s hurtful, but I’ve never fully understood why. To me it’s in the same group as idiot, fool, lunatic, imbecile and cretin. Words that aren’t used to describe conditions anymore, only used as insults. While they can be used with hatred, they can also be used in a teasing way with friends. To me it doesn’t reach the level of racist, sexist and homophobic slurs.
I wanted to learn more and found a paper that makes the case that ableist insults are slurs. Download it here
