Personally, I grew up on a single parent home, where I saw my mom get destroyed by her office work. The lack of unions, no external help and general misoginy, made her get super depressed, and became an alcoholic. In my teenage years I was almost lured by the manosphere communities, but got helped by a group of close friends that were left leaning. Most of them were anarchist, so I started with that. Slowly but surely, I started to understand how sick this system is, and it made me furious, but I never found a way to show my ideas. No political party represented my ideas, and I fell deeper in the anarchist rabbit hole. Yes, I was a hardcore anarkiddie, but I bite me back. When I needed them the most, they turned their backs on me, and fell into deep depression. And in seeking psychological help, my counselor recommended me going back to my roots. So I went back to videogames, japanese culture and most importantly, read again after years The Communist Manifesto. I still don't know how to position myself in the left, but I know that I'm a Marxist, and that I want change. Stay safe, comrades.
It happened in stages.
Seattle in 1999 (if you were there, you know
) was the start, but when 
gate became a thing and the "Pied Piper" ratfucking strategy handed the election to 
soon after that, at some point I came out the other side a leftist.
EDIT: The western response to covid then Jokerfied me.
Then China giving in and lifting restrictions because of treat-hungry boomers of its own was an extra layer of Joker makeup.
