This is the first I heard of the Prager U parental filtering and demonetization. The videos are certainly conservative, both culturally and economically, but the ones I've seen aren't objectionable in any way. In many ways, they are less objectionable than a lot that goes out over the AM radio bands in the U.S. Ars Technica on the story: https://arstechnica.com/tech-policy/2017/10/prageru-sues-you... Best I can find…
Some of the PragerU videos are rather disturbing but I'd rather have them public because picking them apart with friends is quite an interesting activity. They are an amazing conversation starter on a variety of topics. I'd hate it if Google started removing them completely, despite me not even closely aligning to their ideology.
I hadn't watched one before, but I just watched the facism one to try picking it apart. I was expecting something considerably more in line with conspiracy theorist youtuber's I have watched.
Its rather disturbing how the roughly correct facts (I'm not sure about complete correctness as I haven't read much about fascism) are quickly assembled into an argument that conservatism is "better" than liberalism.
