HN has – through inaction – smirkingly enabled alt-right/NRx/GamerGaters to parody-thru-libel liberal positions on equality for a long time; supporting Peter Thiel is in the same vein. That's made Hacker News racist, sexist, and (worst of all for this crowd's self-image), stupid.
For a bunch of "disruptors", they're blind to the systemic effects of that set of decisions to the point of parody. Well, the only conclusion to be drawn: the Y Combinator partners (and the companies they fund) don't care sufficiently about society to be people I want to work with. Makes my decisions easier!
