I think there's an ongoing ret-con meme. Back when the whole Charlottesville thing went down I remember they were saying "You will not replace us" which I assumed was about immigration. But lately I've seen progressives refer to them as saying “Jews will not replace us.”
I'm not saying I know the truth, because I don't. But this is one of those things where one thing can be tweaked and suddenly a different thing is widely accepted.
