You see a lot of Nazi symbolism? Because clearly fascist symbolism is not given a pass. I’m also not sure what you mean by capitalist symbolism. There’s no universally agreed upon symbol for capitalism, the closest thing is the dollar sign and that has a dual meaning.
So please, be more specific (ideally with examples) with what you mean when you say fascist and capitalist symbols. I’m sure if there’s anything specific (like the hammer and sickle, that was purposefully chosen as USSR symbolism) worthy of banning then there’s probably no issue with the removal of such symbolism.
