You gotta be careful about Louis Theroux. I watched one of his old documentaries (late 90s IIRC) about South Africa with a guy who is a Afrikaner that I speak to semi-regularly on the internet. He said that while the people that Louis presented did exist, they were considered loons by the rest of the community.
Most of the documentarians from the BBC even some of the better ones like Adam Curtis, tend to distort things.
The "Red Pill" thing was stolen by these guys back in ~2018 from smaller political communities online that used it to just mean "I've been sold on an idea" usually people who were agorists / libertarians / ancaps.
Thanks for the heads up. For the most part he interviews people with hundreds of thousands or even millions of followers on social media. So not random nobodies, and at least some of the names I’d at least heard of (like the Tate brothers).
But as with anything, being a bit skeptic is a good thing.
