There is not a (net) mass exodus from the Bay Area, hence the ridiculous prices. I moved to SF in 2006 and there were always people claiming it was on the verge of collapse because everyone was fed up with the high prices and crowding and was fleeing. Funny to see that nothing has changed.
“No one goes to that bar anymore, it’s too crowded!”
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?
What gets you in trouble here is talking about pro-life family values, personal responsibility, and how marginalized groups who are over/under represented in certain outcomes must deserve it.
There might be some diversity of economic matterts; depends on whether you make money on walking through the outer fringes of legality (e.g. AirBnB) or not. On social issues that you mention SV is far more of an echo chamber.
Although I do wonder where you're getting the idea about groups that "deserve it". Personal responsibility, vs. identity politics seems to be a rather large dividing line between liberals and conservatives, and "deserve it" as applied to groups is a liberal belief, not conservative.
