White supremacy is nothing more than the majority white people voting for their interests and representation. When a liberal says that he wants to eliminate white supremacy, he is saying that he wants to eliminate the ability for white people to vote for their interests and representation.
They don’t even pretend anymore.
They now say they are against “Whiteness” and want it to disappear.
I think your definition of “white supremacy” puts you in line with what the left believes. I strongly disagree.
