The politics of HN comes from where the users live. Most of the HN users live in tech hubs which are cities where most people who move there absorb the political views which helps them fit in.

Need to fit in is much more important to people than acknowledging the truth... mostly because the fear of being ostracized is one of the strongest and deepest human fears.

The only problem with downvotes is the rate limiting that HN applies to users who are frequently downvoted. Otherwise, I don't mind. I know these people are not downvoting me because they think I'm not adding to the discussion or violating guidelines or anything like that. It's precisely because I'm saying things they know is true but they have shadowed it in themselves and managed to convince themselves with other ideas just to try to fit in. So, when they see it out in the open, they feel very uncomfortable and want it to be hidden. I hope some of them will be inspired by by actions and see these things in themselves.
