it says that these so-called 'anti-fascist' groups are good at branding themselves?

Anyone can start a group and call it "Anti-Fascist" but it's silly to suggest that opposing that group means you're a fascist. Maybe you don't like their methods. Maybe you think they're full of shit in who they choose to oppose. Or maybe they do commit crimes and you call them criminals.
