In a word: overkill.
Because homogeneity is the objective of the New World Order, i. e., absolute conformity to the point of turning everyone into indistinguishable automatons, they fear even the slightest differences becoming a basis for expressing individuality, which in turn could lead to a desire for independence and rebellion.
I suppose the white races should consider themselves lucky, because I believe that many of their non-white counterparts are slated for total genocide under the master plan of one-worldism. At least the white race gets to survive according to this plan, albeit as a multicultural amalgamation of its former self.
