@_L1vY_ History. I'm big into historical documentaries and some light archeology and it's only a matter of time before YouTube tries to sell me "Why the Crusades were GREAT actually" or "the REAL story of the SS." It also seems to have some kind of reverse topic-based mirror, so if I'm watching say Tom Nichols talk about the demonization of trans people in the UK, I will also get "Ben Shapiro DESTROYS Trans freak." I use "do not show me this channel again" a lot.
