“R*tarded” is not used as medical terminology specifically because the word has become a slur.

Nobody in the field, except for very old people (people who’ve been working in the field since the 1970′s/80′s and have yet to update their terminology) uses it anymore. 

So don’t give me that “it’s a medical term” bullshit. It’s a slur and you’re using it as a way to ostracize and other dd/id individuals.
