I don't think that argument applies here because HN is not a general-purpose discussion site. It has a specific mandate which explicitly doesn't cover everything [1], and that's the most important fact about it. Plenty of things are off-topic here, and that's not "robbing the human race" any more than, say, not letting people walk their dogs in the library.

To argue otherwise is basically to say that all sites have to be the same. That can't be right. I think there's a place for a website (at least one?) dedicated to intellectual curiosity. We can't have both that and uninhibited political battle, so if HN is to exist at all, it needs a moderation strategy similar to the one I've outlined at the links above.

If anybody has a better idea, I'd love to know what it is, but please make sure you've familiarized yourself with those past explanations first. If it's something simple like "just ban politics" or "just allow everything", I've already explained many times why it won't work.
