That may be true for you but I don’t think it generalizes to all autistic people. Anecdotally in US leftwing (like actually left not Democrat) political groups it’s very common for the most involved people to be 1. on the spectrum 2. have strong outgroups (eg basically every ML group hates other ML groups) even to the point of it including people nominally in agreement on 99.9% of issues 3. are willing to purity spiral and reject anybody in their outgroup.
