Briefly in 2015 I stumbled upon a blog that covered human biology, and then a couple more interlinked. Kinda got a bad feeling after an hour of reading it, kept on hate-reading it for another few days, realized "yeah, these are racists, bye". Went back to the Wokemon fedbook page and anarchist online spaces.
When Gamergate was happening, my biggest concern with games was "all the people with the best stats are the ones who can afford better PCs and premium subscriptions and other ingame store items". Not having a predictable income to amply support myself made me start to radicalize through my online gaming experience. I think it was on a gaming forum that I was linked to Capitalism and other Kids' Stuff.
