> The SF Bay Area culture is probably not a thing

Exactly. Even if we restrict it down to the million or so people who live and/or work in SF, there are so many different cultures and subcultures that it's impossible to generalize down to any specific culture. This is true of any medium- or large-sized city.

Sure, but again, the same can be said of any medium- or large-sized city. I don't say that to minimize the shitty subcultures you mention, or to suggest we shouldn't own it. But this is just... how society works, for better and for worse.
