Youtube gets way too little blame for radicalizing a large chunk of angry/confused people imo. I watched a video one time that I guess was alt-right-adjacent. Youtube immediately started recommending more hardcore basically racist content intended to induce more anger - leading my right down the rabbit hole if I wanted to go. I had to train it to stop doing that.

Instagram seems to have done the same thing for a bunch of people in the wellness community - pulling them some of them down into the Q-rabbit hole.

I truly despise the algorithms and blame them for most of the problem.
