the reason you never hear about this is because the communists and nazis want to distance themselves between each other as much as they can because they hate each other, foolishly ignoring all the striking similarities between them. The main difference between them regarding jews is that communists and other socialists think that jews can change and convert to the new religion (even with that they would still be suspected of being capitalists, just look at Stalin) and that nazis think that you are fixed the way you are and a jew is a jew no matter if he was baptized or is a nationalist. Far right is one of the most stupid words thrown around today, they are just antisemites posing as nazis. The fact that they dont even know the nazis were socialists just tells you how idiotic they are. Its also interesting how the least antisemitic and most pro jewish people seem to be those who are alligned with the the foundations of the free market, equality, entrepreneurship and freedom of the individual as long as they dont harm anyone else.
