I find the set of topics that programmers absolutely lose their minds about absolutely fascinating.
One example is "furry-style" cartoons. As mentioned in https://twitter.com/altluu/status/1479541394884771847, lobste.rs had to ban everyone who loses their mind when they see these cartoons; before the bans every discussion on a post with these kinds of cartoons turned into a flamewar about whether someone can be taken seriously if they have cartoons on their website.
