As an autistic person I quickly found and fell in with other autistic and otherwise ND folks. That led to long and interesting (sometimes almost overwhelming) discussions and useful, constructive and supportive exchanges of ideas.
Although I'm a cishet male, I'm hugely interested in (and strongly egalitarian about) gender and sexuality. I am also politically left wing.
So most of my regular friends here are some mix of ND, socialist, humanitarian, trans, non-binary, gender fluid, gay, pan, etc (and a few furries).
