It's a term I've used. All 320 million of us Americans have to get along on some terms. We're a big country with a lot of subcultures and variance in needs, experience and standards of living. Defeating fascism will take a majority of those 320 million people agreeing on a complex set of values that aren't fascistic.
We need to be focusing more on finding allies that share anti-fascist beliefs than subdividing into smaller and less powerful factions. The crime of American politics is that we can't more closely align our beliefs with our representation. We are vastly under-represented for our size and technological prowess.
Look for allies, not enemies. It's always easy to find enemies, it's what the Republican messaging system excels at. Find the people who agree that fascism is wrong and grow a big enough tent to defeat it.
