Personally, I was a left liberal for all my life, but had kinda looked into the abyss of anti-sjw and gamergate stuff, like watching Sargon and Bearing, but hadn't really subscribed to their beliefs, more putting them on as background chatter.
Things changed when I read manufacturing consent, listened to Chomsky and found Chapo at around the end of 2018, at which point I found myself as more an ancom, but Chomsky's talking points on Leninism and the USSR was never as cogent and didn't make as much sense as his other points, so I held skepticism about my beliefs then.
Reading more on theory and history, and looking more into different left tendencies via channels like Rev Left moved me over to be a Marxist, as it made the most sense to me in explaining the current and historical situation. Currently making my way through Lenin and looking more into historical ML states and I've found that I'm pretty comfortable as just a Marxist with ML tendencies rn.
If you're short at that age, it can be encouraging to know you can still successfully grift off vitriol if puberty decides to vertically fuck you.
