You do see this kind of solidarity in the streets: I protest with people of all different non-Nazi views, from Never Trumpers to actual communists. Sure, there's infighting sometimes, but the movement is working because most of us are willing to put our differences aside to focus on the main problem of fascism. It's a relief to see some leaders doing the same. You cannot and should not engage in "bipartisanship" with Nazis, but it's great when the rest of us work together.
