this is an interesting asymmetry I've noticed too. There are countless of places where salt of the earth Americana is the de facto monoculture.
If I'd go there and try to create a liberal-hippie space for myself they'd probably flip me the finger and tell me that's not the local way of life, and somehow everybody seems to agree that this is perfectly fine.
Yet when people in the valley or in a big city share a common culture they somehow have to defend themselves and painstakingly carve out a space for Peter Thiel et al. Why is that? If he doesn't like California's culture Thiel can move, end of story. Why do we have to treat him like a wounded deer?
