Most online platforms I have used to ask questions or make comments (whether it's real-time chat, mailing lists, forums, etc.) were extremely hostile and always have been... I guess it's just human nature.

StackOverflow, Reddit, Lemmy, Matrix, IRC (esp. Freenode/Libera), Mastodon, Bluesky, Lobsters, Phoronix, GNOME Forums, Discord, Twitter, LKML, ... over time I quit all of them because of just how unbelievably abusive, dogmatic and out of touch people were.

Even on HN I have had to block dozens of different accounts due to breathtaking entitlement, self-righteousness and arrogance.
