Wait, do you really believe what you're saying? You realize that YouTube has to appeal to advertisers to make money, and advertisers don't typically like sharing platforms with every group. If you crawl through new uploads, you'll find literal neo-Nazi propaganda without even working that hard.

There's nothing illegal about being a Nazi (at least in the US), but advertisers typically don't want to be on the same platform as Nazis (for good reason). Are you claiming that advertisers should be forced to advertise on platforms that they don't agree with?

NOTE:

I'm not claiming that PragerU is outright Nazi propaganda. I think they're a terrible organization and their videos are idiotic, but I haven't seen outright Nazi promotion on their stuff (though admittedly I haven't watched everything by them).
