I became a commie at 11. Fucking 11. It was on Quora when it first blew up. And I mean a hardcore tankie, holodomir denier(still don't think it was ethnically targeted) USSR apologist, so on so forth. I joined multiple Discords and they are exactly like you think they sound. Luckily, I was given a break so I wasn't constantly exposed to extremism, but I'd say I was the equivalent of an SJW until I was 13. Then I became a full blown Nazi which lead to me getting into a fight at work when I was doing summer jobs to get a new gaming PC or whatever the fuck was on my adolescent mind. As I had harder and harder curriculum in high school I had less time to focus on that stuff. Now, as an adult, I've settled at reactionary liberalism. It's been a wild ride.
