so OP’s probably a leftist (like far left, not Democrat) and probably a Marxist; assume when leftists say “liberal” they mean “capitalist” or “status quo”
so they’re saying that the person they’re replying to thinks that the status quo narrative is somehow apolitical, and thinks that that’s not only flagrantly incorrect and self-absorbed but proving that people like that guy think that their beliefs are just how the world is instead of like actual beliefs that people hold on how the world ought to work (politics)
