I'm diagnosed autistic and I approve of this usage. I would be grateful if normies would refrain from getting offended on my behalf, I'm plenty offended enough by other things.
I 100% understand frustration of outsiders of a group being offended on some other groups behalf. I'm in a particularly progressive part of Canada so it happens a LOT! :=D
If it helps at all, I was talking on behalf of myself, not yourself. That being said, the term "normies" also irks me, so clearly our differences have nothing to do with our position on spectrum :->
(neither "offends" me, but as per above, I automatically take less seriously the user of such words)
