/jp/ - Otaku Culture

This is probably a tired question, and it may seem like I'm just trolling, but I really don't understand the overlap: What is it with the prevalence of trans and communist in the rhythm game community?
I've never seen such a high occurence anywhere else. Is it just me? Or is it because I'm in the sows discord?
Slightly less related, but what's the deal with people into rhythm games being into, I guess it's "car culture"? I make friends with people who are into rhythm games, and I think "finally some cool guy to talk about my autistic obsession", and then they always start sending me links related to one of these things. Cars, trans rights, communism. I don't get it. I just want to play rhythm games with my fellow shut-ins.
