You could literally prove yourself wrong by exercising just a little intellectual curiosity. Marxism is, at its core, an economic theory based on the idea that democracy has as much a place in the workplace and economy as it does in our political system. If that’s fascist to you, you’re unserious.

Now, if you’re just unwilling to correct or criticize your own beliefs, and you want to conflate Marxism with Stalinism and Tankies, you’re better off just saying so.
