One of the things that IMO helps HN a lot is that it de-prioritizes politics (at least hotly debated topics,) in part due to the rules, and in part simply due to having something else to talk about.
I don't think politics in general as a topic should be banned, but there is exactly zero intellectual gratification in reading a thread where I can predict without reading what the opposing sides are going to say and the respective counter-arguments.
I just can't see how thread #32768 about affirmative action or thread #65537 about abortion can be more interesting than the previous one. You'll just be served defrosted opinions.
HN is one of the better places by far, and I think it takes active action by someone at the top to hold the line.
On here we also get extreme reactions still though - The only reason apple does X is because they are evil and want to spy on you etc.
One idea you see in nature and also developing countries is camouflage. You basically give your kids a very generic name so they blend in, harder to search etc. In developing countries people really operate with nicknames a lot more and sometimes have multiple "real" names.
