As a leftist, I find the notion that SV, northern California, or the likes of Google, Facebook, etc. have a left bias to be hilarious.
Most companies choose to get rid of jerks for a ton of sensible reasons. In a libertarian ideal they'd be free to choose who to hire/fire.
Large groups calling for someone to lose their job is totally in line with libertarian ideals. Nobody is calling for government regulation, this is just the (employment) market at work.
I don't think the SV crowd gets how reasonable the author looks to everyone else and how unreasonable the angry rants on Twitter look.
Maybe this just says more about our individual social groups ... or one of us is wrong about how prevalent one viewpoint is vs the other. Could be me :)
