There are similarities, and it's not uncommon for someone to be both, but also...I think a large reason I've always found it easy to relate to autistic people (and a lot of autistic people seem to gravitate to me) is that it's great to connect with another person who doesn't decide for me what I mean, doesn't assume malice or carelessness when I didn't meet their expectations, and doesn't react with hostility or disdain to deviation from social norms.
