?? I asked the question more because I was just curious if there are legitimately like mid-30 year old groups of friends that haven't grown out of this "4chan attitude" of using the n-word, calling people "autists", etc.

I didn't ask out of a sense of voyeurism. More like a, "dang, is this something I need to watch out for when I get older?"

This is precisely it. A willful ignorance when referring to awkward people as "autists" along with tasteless WSB quotes.
