For reference, this was the Instagram post that got her fired:
"Jews were beaten in the streets, not by Nazi soldiers but by their neighbours...even by children. Because history is edited, most people today don’t realize that to get to the point where Nazi soldiers could easily round up thousands of Jews, the government first made their own neighbours hate them simply for being Jews. How is that any different from hating someone for their political views?"
So not outright hatred of any other groups, but she's basically trying to equate "oppressed" Republicans being generally shitty people to Jews during the Holocaust. If anyone in America is promoting hate at this point in time though, it's Conservatives and Right-wing media.
