Hmm I see your point- but if what they did was called 'rational' then there has to be another word for the part where they made the mistake. The mistake was they came to so much of a conclusion about something that they acted on it. They were wrong. They caused negative utility. It negatively effected the world and also their understanding of it. What is that called?

But why do people just accept the status quo?? Politics doesn't kill my mind. I know how to not 'cheer for my team' and to think about topics in a balanced way. I expect people to act irrationally on the comment section of the news website I read- but why are people not rising above it on this website of all places?

Get use to it? It's very hard to think it's rare and unexpected for people to talk about a topic rationally. I don't see why people find it so hard- especially when they've apparently read articles highlighting common problems and where they come from.
