I'm 100% neurotypical and and find that pretty much every community is just a bunch of relatable memes. ADHD, Autism, Bi-polar disorder, depression, etc.
Same thing with all the various sexual identities. I'll call out bisexual people because I think most of them will admit it: they'll take literally any behavior and appropriate it as a key element of bi culture. Lemon bars? Bi. Bad sitting posture? Bi. Cuffed jeans? Bi. Finger guns? You're not a goofy sitcom character, you're bi! Appropriating any innocuous behavior as part of your sexual identity's culture? Bi!
I've got no problem with it. Anything for more good memes.
It's not just bis. Gays do it to. I found out from Reddit gay subs that I should be a fast walker. Apparently gay people all walk fast. Not something I've ever noticed.
It's funny how innocuous stereotypes sometimes get popular like that. In ten or twenty years that stereotype will have been repeated by the current generation so much that the next generation will find it offensive.
