Right, if you stop at the idea alone, but take actions into account.
okay both ideologies had governments that were war-mongering and both systematically executed the rich class in their society
fascists believed that jews had sold out their country for monetary gain at the end of WWI, so they went after the Jews
it was easier, too, because they had a moniker to label the "greedy rich people" with as opposed to the communists who just had "grrr rich people"
they weren't tribal
therefore they went after the Jews, they saw the Jews as the communists saw the rich people of society and
therefore went after them and that made them tribal
they're literally not different
