Yes. Still, it is irrelevant if Nazis were left-wing or right-wing. Everyone knows Republicans always use fallacies in their arguments.
But you’re falling victims to their fallacies by trying to show that the left is not associated with Nazis. Who cares if the Nazis were left-wing!!! That is totally irrelevant. Stop playing their game. If the past associations are relevant, then they could use the communist card and show what the left has done in other countries before, like North Korea.
