HN is extremely (American) left-leaning. Do you not remember the threads about the murderer of the health insurance CEO? Any thread about US politics? Or just the simple fact every thread about office politics or workplace relations is VERY pro-unionisation, VERY anti-manager. HN highly favours higher taxes, higher minimum wage, trade unionism, work from home, open borders, net zero etc. Of course it is an American leftism rather than European leftism or Commonwealth leftism which have different focuses.
They're probably in the minority here like they are in real life, but there's plenty of right wing extremists, just scroll through any politics trump/musk thread in the past few weeks and about Israel for the past year.
Even the current administrations project 2025 comes from right wing tech extremists (mixed with christian faschists) that believe that tech CEOs should be feudal kings in a broken up America, I don't think any website is closer to this than hackernews.
Honestly, until very recently, I haven't felt that at all. Just look at the thread on Trump winning the elections. You might be right in that the majority of users may be democrats, but that doesn't mean they are all pro-union, pro-redistribution, etc.
I wouldn't call management-bashing leftist, everyone engages in that, even if right-wingers refuse to go further than individual action.
I personally fucking love rockets and what he did. But for the past years made me hate the man.
My guess is that most people here are center-right wing, or at least a majority of HN isn't left-leaning.
It's surprising he managed to make even that audience hate him
