> I think the bias of Wikipedia is pretty clear polar to that of PragerU
As if. This article: https://en.wikipedia.org/wiki/Holodomor_genocide_question is still up despite having almost zero pertinent sources.[1] Calling that "polar" is nothing short of a stretch.
At most, Wikipedia could be said to have a neo-liberal bias, an ideology upheld by both of the US' political parties, based on policies alone and not on each individual voter's personal and nuanced adherence. The parties are wrongly assumed to be polar opposites on the political spectrum by most US citizens, but they're not.
