On politics, Hacker News itself isn't right-wing, at least most of its users aren't, but the fact that anything more than a standard deviation to the left gets you hammered through that passive aggressive rank-altering and "slowban" has really put a damper on the ability for people to indulge their intellectual curiosities. Simply asking whether we, who "hack" in service to corporate capitalism, are doing the right thing, is enough to get you in trouble.
There are some absolute top-notch people posting here, but there are far too many corporate shills, and the good ones know they have to be careful.
