That is literally how leftists define "white supremacy"

They redefine words so that their use only makes sense within their own ideological framework of dumbfuck ideas

Its like how they believe that you can't be racist against white people because they believe western civilisation is set up so that white people.have power and privilege at the expense of minorities.

Leftism is not just one or two bad ideas, it's a circular, self-referencing, self-contained alternate universe of bad ideas.
