I suspect that youtube is intentionally flinging these assholes' content at younger men beyond what would be expected of the algorithm being left to its own devices. Facebook does something similar in that their algorithms were intentionally designed to result in polarization in a general sense. Conflict and extremism generates more profitable noise than reasoned debate does.
Reddit does this too. They pretend that they're a "bastion of free speech" (when it suits them) when in reality they like the conflict that results from extremist views generating more profitable noise. These companies are doing what the profit tells them to do and the profit is telling them to nudge content in a direction that could very well eventually tear society apart.
