This theory isn't necessarily true. I live in NYC, which is very secular.
Having a love life as an Aspie is impossible here, too. I have spoken to disabled atheist people here. They nearly all say "I haven't had a partner in 7 years!" Or "I am 30 and still a virgin!"
And when they do attract someone, it isn't even a relationship. It is this weird, desperate, pathetic thing that quickly ends.
