Here are the new definitions of these words that you need to understand:
"Black" = "One of us"; Marxist-Leninist revolutionary; leftist; Member or supporter of BLM; American slave or descendant thereof, or spiritual/fraternal descendant thereof [and remember that only America had slavery, slavery is America's "original sin" and it was based on race]; victim; innocent in all circumstances; incapable of racism.
"White" = "NOT one of us [even if of sub-Saharan African descent]"; NOT a Marxist-Leninist revolutionary, leftist, BLM-supporter or Democrat; believer in the founding principles of America: the Declaration of Independence, the Constitution, the Bill of Rights, freedom of speech (and of silence), the right to self-defense, etc; oppressor; enemy; guilty in all circumstances; irredeemably racist; most racist of all if denies being racist.
"White Supremacist" = "White" (even if black) person who by word and/or deed actively defends the principles of "Whiteness" like work ethic, punctuality, deferred gratification, good grammar and manners, and the whole Greco-Roman Judeo-Christian Magna Carta English Common Law inheritance of America.
One quickly realizes that "White" and "Black" have nothing to do anymore with actual color or race; it's beyond just White is Black and Black is White, if it were possible to be more opposite from original meanings. It's about taking sides in a philosophical and physical war that the left is waging against America.
