I fit into your group of males in a stable relationship with no friends beyond that. But I'm an introspective sort of person and I find it more interesting to interact with random strangers on the Internet than I ever would with a friend who I already knew everything about. I'd probably run out of anything to say to any particular person after a while that isn't repetitive.

That doesn't mean I'm going to get sucked into to some kind of tribe like a political party or a religion. Or maybe it's just as accurate to say I already got sucked into a scientific outlook and scepticism at a young age and now find it impossible to escape.
