it’s not ableism to ask someone to quit a behavior if it’s harmful
Autistic people can understand the word no and bigotry isn’t a symptom of Autism so you’re allowed to tell someone off for being a bigot.

ADHD and Autistic people can stop a hyperfixation or special interest if the material they’re consuming is harmful. You just have to let it die out, even if it makes you feel happy, it’s better to not hurt others by giving money and attention to something that was built to hurt others
People with personality disorders can follow set boundaries. Having a pd doesn’t mean you can trauma dump or force people to only respect your boundaries, and you’re allowed to leave someone if you’re unhappy in a relationship of any kind with them no matter what pd they have
People with delusions can be told to stop spreading conspiracy theories or talking about their delusion in public spaces.

As someone with several neurodivergencies and personality disorders as well as other mental health problems, I can say firsthand that the bare minimum expected is to cope with your symptoms in ways that aren’t destructive to others.
