So what is the game here? Put a random noun between "…" and "?"?

Let me try:

…airhockey?

Are you trying to communicate or be a dick? The only universal value I am aware of in san francisco is capitalism.

I would ask the same thing of you. Are you playing dumb or are you really not aware that SF is kinda out there on the U.S. left wing?

If I, a european who've only visited the U.S. a handful of times, know more of U.S. politics than you do, I really don't know what to say.

It’s only left wing in a very meaningless definition of left wing. I live there :) San Francisco hasn’t deserved the reputation for decades at this point. It’s the stronghold of Pelosi, a neoliberal and a staunch centrist. Ditto with Feinstein.

It sounds like you have no clue what "left wing" means when you refer to capitalists as "left wing". Because generally, it refers to anti-capitalists (socialists, anarchists etc).
