It’s a Communist meme. Liberals are correct when calling conervatives fascists, they just don’t realise that Liberalism supports the material conditions that result in fascism.
I think like… Rocks aren’t political, until communities of humans arrive and start talking about rocks and using language to describe rocks. A rock that humans have never interacted with isn’t political, until people start using it as an example of what is and isn’t political. Sort of like quantum but for concepts and relationships being perceived by communities of people.
France is speedrunning this right now. Any time a liberal claims to be antifascist, ask them to explain why they think fascism exists and where it comes from, materially.
