> I have no idea what SF is like, so in these discussions I never can tell if there really is an influx of insane, insufferable far left crazies

I'm not a Trump supporter by any means but I remember clearly the morning after the election and seeing people walking through the street in SF on their way to work in tears.

If that doesn't point to a presence of insane, insufferable far left (or at least leftist) crazies I don't know what does.

It was very difficult not laugh.
