Surprisingly many topics are political [1], and an answer the very right-wing libertarian consensus here disagrees with will absolutely be voted all the way down.
[1] Often, the assertion "this topic is not or should not be political" is political. Because politics is how we organize society on a large scale and saying things should be exempt from that, guess what, is a political opinion.
Dunno, I'm pretty sure I've seen calls to break up or even nationalize Google and similar sentiments at the top quite a lot. That doesn't strike me as particularly right-wing?
I actually agree, I just think libertarian right wing is a mischaracterization, and I think it matters because the stereotype of the tech nerd is the atlas shrugged-toting libertarian, but HN doesn't really match that stereotype most of the time, I think.
1. Comments cannot fall below -4 points
2. Downvoted comments only get greyed out, not hidden entirely
3. Most topics on HN are not political (though there are certainly exceptions)
4. The community here is (usually) a bit more mature than on other sites like Reddit
