How do I become not ableist?

TW: ableism???

I don't HATE autistic people but I just kind of feel cringed out and uncomfortable near them or like I'll say something bad and that'll make them think I'm a dumbass (which I kind of am but that's unrelated). I kinda hate that cus 1. It rly limits the amount of people I can show love to and 2. It's a sin to be rude and stuff.

I try to simply distance myself from them to not hurt them but that might be kinda bad too cus what if they need something and I wasn't there to help? also I kinda feel like if it turns out that I am autistic I'd probably just kinda go kms or smth idk sry if I sound rude
