Lisa Guenther has, with Abigail Levin, an op-ed in The New York Times on white nationalism in the US, 'White Power and the Fear of Replacement'. Levin and Guenther argue:
In the context of these movements, “You will not replace us” reiterates the core message of slogans like “All lives matter” and “White lives matter.” It’s another way of reasserting the supremacy of whiteness and its irreplaceable, but precarious, value in a fundamentally confused zero-sum game where one group’s gain must equal another group’s loss. From this perspective, “You will not replace us” means something like, “White lives matter uniquely” or “You will not make us feel like we don’t matter by asserting that you do.”
