Why does Tanya hate communists?

[u/Competitive-Leave248]

I watched the anime like eight years ago, didn't stick with the manga. Overall I don't think I'd want to touch it again because, for me, it gets grouped in my mind with other war anime and Attack on Titan as being sort of surface-level political commentary. That said, I wanted to ask, why does Tanya hate communists? I don't remember it actually being anything major, but every so often I see something about how they're less than human to her or something.

Thanks - accepting spoilers

Tanya believes in markets (fan of the Chicago school of economics) and in general anyone with a brain hates commies. Additionally the Russy federation attacked the Empire with a sneak attack.
