There’s that post that’s like ‘everyone should get into a tiny niche fandom at least once’ fully agree, that was really fun -- but I would like to add that everyone should get into a fandom where their opinions run counter to major fanon because it really teaches you about sticking to your guns and trusting your interpretation of the text without having to rely on peer validation
I think we should have a turn of phrase for "I'm not in the right, but I AM annoyed with this situation, so I just need to go bitch to a friend about this before I suck it up and go do the right thing" because more and more I'm finding this is a critical element of functional adulthood.
