There's a lot of frustration and shame in it, too, because of the way the world as a whole treats us. I think it is rooted in Aspie supremacy or whatever (internalized and external), but there is so much focus on the so called magical, wonderful abilities autism gives you (in my case, raccoons/costume design), that when you exhibit autistic traits more commonly associated with "high support needs" individuals, people automatically go "ummm I think you are faking/lazy/stupid/weaponizing incompetence/blah blah blah because I have seen you do [xyz thing that people find incredibly impressive], so you should easily be able to do [current thing]!" When that is not how autism works.
Additionally, I don't think most people realized that a lot of "low support needs" autistic folks aren't infact all that "low support needs," it's just that they don't have people able to meet those support needs, so they just struggle. And because nobody is there to see them struggle, then those struggles don't exist.
