According to racist Liberals like this, almost everything is White Supremacy. Civilization, Rule of Law, Basic Intelligence, Good Manners, Civility, The ability to speak correct English, Keeping a Clean House, Eating with plates and silverware, Having no Felony Record, Taking a Shower every day, Wearing clean clothes, Using Deodorant, all are White Supremacy traits.
Essentially, being a clean, normal, intelligent, educated human being, is White Supremacy. That is why Liberals apply the term White Supremacy to any race, including Black people. Because the way they use the term, it is not about race. It is about a wholesome, honorable, successful, way of life. That is what they hate, no matter who or what race you are.
