This site is incredibly censored. Their mod system is very gamed with people who know how to build up credit and downvote en masse.
Whether or not the founders support this behavior, it exists. There is a nasty, nasty f-in power culture that censors people along a political power axis these days. You cannot understand YC/HN without understanding this puritanical (left-wing) culture that has burrowed its way into VC backed companies.
Ignore me, dismiss me, whatever. But the censorious culture of the Bay Area is the very opposite of the (pretty neat and good) hippy dippy free culture of the 60s. It's the reason people are leaving, because their free-wheeling ideas are encouraged elsewhere.
You clearly don't know what "left-wing" means if you think that a bunch of upper middle class highly compensated engineers are that... Actual "left-wing" comments on HN are generally downvoted quite intensely.
EDIT: I just want to add how ... odd... it is to slap a "left wing" accusation about YC-backed companies as we sit here on a thread talking about a YC-backed company that was basically a loan-shark pay-day lender. WTF? That's left-wing? Ok then.
