Most of us are quite familiar with what's talked about here. Try not to get hung up on the term "white nationalism". One thing to point out is the Youtube algorithm they mention breifly....try watching something by Ben Shapiro & see what happens to your recommends for the next 50-odd page loads. Youtube seems to be favouring particular channels. It's possible it's purely a product of the creator's overall exposure on Google. Shapiro has like 80 staff to promote his content.
What I find strange is how many of the right-wing reactionary youtubers are Canadian. Seems like most of them.
NZ's most popular conspiracy theorist/political commentator is a friend of a friend & apparently he knows what he says is mostly bullshit, he just plays the game for the $$. I'm 99% positive Alex Jones is doing the same thing.
