I think there's another factor here not mentioned by other commenters - it is possible to be both neurodivergent and an ass, but it can often be a lot easier to discover that a neurodivergent person is an ass. Neurotypical assholes will usually be pretty good at controlling their public image.

So even if we suppose that cancel culture somehow has 0 false positives (which I highly doubt), it's likely that many more neurodivergent assholes will be "caught" than neurotypical ones. Which feels functionally very similar to profiling IMO, and practically means we are probably not catching the more "dangerous" assholes. Because it's a lot easier to ignore an asshole view if you're aware of it.
