The Great Replacement is the original name for White Replacement Theory (WRT). I suspect that leftists made up the term WRT formulaically: “The right accuses us of CRT; well then, let us accuse the right of WRT.”
I suspect this because — as the progenitor of the topic (Renaud Camus) has said — the Great Replacement is not a concept, it is a phenomenon.
I don’t know if there is a conspiracy of global elites, deep state rulers or brown supremacists to accomplish the Great Replacement, but I do know that demographic replacement is a fact of life. The question is, How should we think about it?
My view: We should acknowledge that changing the racial/ethnic characteristics of a society must have consequences that deserve discussion. Further, we shouldn’t let big concepts (or ideology) dictate our eye-to-eye relationships.
