Opinion answer - no, judging by the votes and contents of the majority of the comments about politically charged topics, I'm pretty sure that most of the people here are approximately center-left leaning, and more libertarian than authoritarian leaning. Some examples, without judging them - HN on average seems to support European worker protections than USA free for all stance, at the same time EU bureaucracy and red tape is mostly universally frowned upon as a factor slowing down economical innovation. Ukraine and Taiwan are supported more than Russia and China. Palestine/Israel opinion seems to be a split, but subjectively it seems majority leans pro-Palestine. Trump is universally reviled, I haven't seen any pro-Trump comments here (at least above 0 votes). Musk is a split opinion, but also majority seems to be against him this year. Megacorps are widely disliked, with a new anti-Google topic popping up very regularly, same with Facebook and Amazon, unless they are strictly about new good IT stuff. Creepto is mocked by majority, anarcho-capitalism too. Aaron Swarz is universally liked as are others with the same leaning.

All in all these are definitely not right wing opinions.

What's funny is that OP thinks anti-Trump posts being flagged suggests HN is pro-Trump, while not noticing that pro-Trump posts don't exist here at all. Unless they're deleted immediately (seems unlikely), people with that opinion have just learned to keep it to themselves (or go away) because it'll only destroy their karma here.

That suggests that HN leans heavily anti-Trump, but also doesn't want to talk about him all the time, so flags posts that drag the forum in that direction. Ditto Musk and "fascism," whatever that's supposed to mean nowadays when everyone to the right of Mao gets called a fascist sooner or later.
