Some of that you may experience as 'dubious political stuff' and 'patently incorrect takes'.
Edit, just to be clear: I'm not saying HN should be unmoderated.
So there’s no reason to try a lot of the tricks and schemes that scoundrels might have elsewhere, even if those same scoundrels also have HN accounts.
I think I never downvoted anyone on hackernews yet - it just does not seem important.
On reddit on the other hand, I just had to downvote wrong opinions. This works to some extent, until moderators interfere and ban you. That part made me stop use reddit actually, in particular since someone made a complaint and I got banned for some days. I objected and the moderators of course did not respond. I can not allow random moderators to just chime in arbitrarily and flag "this comment you made is a threat", when it clearly was not. But you can not really argue with reddit moderators.
It’s true that HN has a good level of discussion but one of the methods used to get that is to remove conversation on controversial topics. So I’m skeptical this is a model that could fit all of society’s needs, to say the least.
