When your brain hasn't fully formed yet you're just looking for answers and when someone shows up who to give you direction who is sympathetic but still marginal enough to be edgy it's a pretty easy sell. Just turns out that Peterson was marginal because, y'know, he's a misogynist homophobe. But since you already trust the guy then you listen to his explanations about what men are supposed to do and what women are supposed to do and clearly he's got it all figured out so there might be some sense to it. That's how radicalization works, right? Someone plants the seed, like Peterson, and over time you find farther and farther right-wing people to walk you down the path until you're full blood and soil.
