Yes, that old psychological affront, where someone tells you "you're not OK (but I am)".
Basically, lumping us in with other people who've got mental illness per se (like bipolar, schizophrenic, psychosis, disassociative personality disorder, or even PTSD).
I got it a couple of times in the past, usually after I snapped and got really angry and broke something - like on a couple of occasions with housemates, but never in the workplace. I got it at school a few times, including in uni. But I can't recall getting the comment purely on the basis of miscommunications or misinterpretation of mind-state, or making social faux-pas. When the toxic person told me this comment, I just deflected with "with you??! yeah,
anyone would be in need of help, you'd drive them insane."
Kind of a narcissistic reply, but sometimes, you gotta
If you wanted to really rub it in their faces, again along the same narcissistic lines, say "Yeah, been there, done that -but I actually ended up being the one who educated the so-called professional." (don't laugh too hard, this has actually been true for me more than once
)
So, yeah. My guess from my own experience is the anecdotes of other Aspies would be along the same lines: you don't get this sort of offensive comment based on the "primary" manifestations of ASD/HFA, but rather due to the comorbids and reactions, e.g. depression and anxiety causing us to act out, be short-tempered, give a piece of our mind to those who intentionally ignore or invalidate us, etc.
Something along those lines, I was told on an autism forum to "be a better person" by an NT parent who later had their children taken from her due to abuse. If only she had listened to what I had to say maybe she wouldn't have beaten her children, when people know you are autistic that pretty much invalidates anything you say, in my country anyway.
