I don't think anyone needs to do anything they don't want to. However, I do believe that if we can't even give each other the benefit of a doubt, some kindness and empathy then what hope is there for us to expect that from nondisabled and neurotypical people to us.. It's really not easy to be considerate, otherwise, we all would be, but I think we should do our best.
My experience has been that in autistic communities there is almost just as much bullying and fighting with each other for their differing autistic qualities as there is in nt-world for their differing qualities with autistic people. I think we as autistic people sometimes put our own very narrow concept of justice above everything and everyone else. We can be very judgemental and stubborn and that is not good for anyone in the long run and makes it hard to create safe and supportive communities.
Thirdly people on the spectrum have such varying needs of accommodations and assistance, some really hate being considered disabled to begin with, so I think there will always be some form of hierarchical thinking in the community about people with other disabilities, which I think is icky. Also because there is so much overlap and many autistic people have also other disabilities.
Anyway you don't have to like or befriend anyone you don't like just because they have a disability but you should have some solidarity if you wish that others would at any time stand up for your rights or be considerate to your disability as well or you are a hypocrite.
