They kept glorifying Jews, the entire series could have been renamed "Jews are Great, Europeans need to die". They kept dragging out fringe theories that have absolutely no traction in the scientific world, and glorifying them. If you looked up the theories, if you could even find them that is, it'd always be made up by a Jew. Even if they did have to begrudgingly concede that the theory was made by a White person, they'd still somehow figure out how to downplay it and make it about Jews. They also took every chance they could to take shots at Nazis, while also downplaying Soviet crimes. Even when it was completely 100% the Soviet's fault, they still attempted to blame the Nazis.
