2. Replace is the operative word there IMHO

The Great Replacement (French: Grand Remplacement), also known as the replacement theory,[1][2] is a white nationalist[3] conspiracy theory[4][5][6] which states that, with the complicity or cooperation of "replacist" elites,[a][4][7] the white French population—as well as white European populations at large—is being demographically and culturally replaced with non-European peoples—specifically Arab, Berber, South Asian and sub-Saharan Muslim populations—through mass migration, demographic growth and a European drop in the birth rate.[4][8][9] This theory is popular among anti-migrant far-right movements in the West.[10] Scholars have generally dismissed the claims of a "great replacement" as being rooted in an exaggerated reading of immigration statistics and unscientific, racist views.[11][12]
