Why are most people with autism left-wingers/liberals?

I have observed that most people with autism are left-wingers/liberals, why is this? I have heard of some right-wingers/conservatives with autism, but not many.

This is just my own personal observation, this is not meant as hate towards left-wingers/liberals or anything. I am a right-winger/conservative myself, but I respect everyone for who they are regardlessly.
