Not on the spectrum, but why do some people make it their whole personality?

Maybe it’s just me, but I always see people who talk about their autism after every 2 words. “Have you heard of (show im interested in)?” “Oh yeah I love that show!” “Im so obsessed with it, probably because of how autistic I am!” Why do people do this? Like no disrespect at all but usually the people i see do this are the people that self-diagnose themselves on tiktok with “silly:3” humor and the people I KNOW have been actually diagnosed don’t need to bring it up every 5 seconds. Why are we romanticizing something thats a genuine, real issue? People get bullied for this and yet we say this like it’s just some silly little quirk about them.
