Aron Ra did a good take-down of one of Prager U’s videos
RationalWiki on Dennis Prager and his Prager U:
Prager “University” actually presents history and politics from a hard-right point of view. This includes rampant New Dealdenialism, promotion of the Laffer curve, Europhobia, and an off the walls weird interpretation of liberalism. The channel also promotes zionist pro-Israeli politics, claiming the IDF to be the “World’s Most Moral Army”,, and promotes fossil fuels as being “the greenest energy”. It has called wealth income inequality “good”. In a multitude of ill-informed videos, it furthermore espouses Climate change denialism, militarism and American exceptionalism, and probably many more nutty reactionary beliefs.
