This just isn’t a site for arguing politics, if you do it too much with opinions different from the hive mind you get banned for disruptive behavior
you'd have to do additional analysis to find which accounts stopped posting after the linked warnings though. It's not usually the opinion itself that's the problem, but that users with controversial opinions have other things going on, so the controversial opinion is often delivered in a “wake up sheeple” flamebait persecution complex “in smart and everyone here is an idiot” style, which isn’t conducive to constructive debate.
My claim isn’t “nobody gets banned from HN”, it’s “nobody gets banned from HN for having unpopular opinions”.
The parallel comment has very nearly invoked Godwin’s law, so I guess I’ll concede that if your opinion is “a group of people should be killed”, then yea, expressing that opinion would likely end in a ban. We can debate how much of that ban is for the opinion vs calling for the murder of other humans.
I'd call that controversial.
If you don't have showdead on, you should.
We have a great example via the flagged reply in this comment tree, where somebody is complaining about being silenced and their example is full of rambling invective yelling at the moderator.
Basically the topics you might see in mainstream news are usually out.
Well yea, that’s officially part of the guidelines: “ Off-Topic: Most stories about politics, or crime, or sports, or celebrities, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic.”
I am generally very happy with HN’s moderation, but I do feel some borderline topics that have been banned or buried missed interesting discussion. I don’t fault those responsible for not wanting to deal with the potential mess though.
