Somehow we've found ourselves categorizing groups of people in the most reductive ways first. People aren't anti-racists; they're protesters. They aren't male chauvinists; they're trolls. They aren't Kurdish leftists; they're terrorists or freedom fighters, depending on who you ask.
This is a result of the ideology of tactics essential to liberalism. This ideology says that tactics are ethical only when they are legal. So of course Antifa are on the same moral footing as Neo-Nazis. They're both Protesters.
When we talk simply about rioters, guerrillas, or terrorists, and fail to ask about their context or perspective, we reproduce the language of liberalism. This hegemonic language is not just biased toward liberalism. It is politically reductive, and impinges on the analytical, contextualizing, and humanistic possibilities of discourse at large.
