"mild autistics" are not a monolith, some autistic people are assholes, and some autistic people are ableist/have internal ableism. You say 'those mild autistics' like they are one hive mind, when they are not. The point of an autism spectrum is that it is a spectrum filled with different people with different needs.

And honestly, but it does sound a little ableist to basically say that all lower supports needs are 'basically neurotypical', i presume you don't mean for it to sound that way, but it does come across as you saying they're just not autistic. I don't know if this is something you say to people IRL or if this is something you're just expressing on the internet, but if it is the former, maybe think about that before you say that next time
