Blacks assume that anyone who’s not lily-white Caucasian is at least tacitly on their side, which ups their 13th percentile of the population to something much larger. They have assumed this since the late 1960’s.
Millions of Hispanics, Asians, & Middle Easterners are ready to disagree. Violently.
The Hispanic and Asian cop killed by a black Muslim sympathizer in New York certainly proves that the division isn’t as easy as black and white.
The other challenge is the “Knockout game”, where Asians, Middle Easterners and anyone simply light skinned was attacked, like those along the Chicago shore. Too many “non-white” people attacked on the basis of pale coloring alone is proof that the blacks involved were racist on skin tone but not caring about the demographics of the victims except “not black like me”.
