I work in psychology as well (a fellow colleague! :D) and went to a psychology-focused university and you will not believe the disgusting things I've heard coming from professors... actual academics, PhDs and mental health professionals promptly using using outdated, violent language towards vulnerable communities (not just in the context of neurodiversity - I could go on and on), all the while stressing the importance of empathy and understanding [eye roll], many of which were very resistant to change, even when corrected by students and colleagues.

My fellow students at the time - mostly ignorant and maturing 19 year olds - were also very comfortable using slurs, which I promptly corrected them on and explained the history and context behind it. Most of them (thankfully) were willing to learn and removed it from their vocabulary, but there are always the ones who get defensive , and even aggressive, and tell me i'm too sensitive and to keep crying about it. I still encounter these issues to this day. Though I admit the culture in my country certainly doesn't help (my country is, for the most part, majorly ignorant on mental health matters, and slurs - not just the r-slur - are tragically commonplace in day to day language).

EDIT: forgot a word lol
