What you say is correct, but it is not really the primitive cultures which are doing the attacking. They are mere pawns being used by the progressive Left to achieve their aims. The Left's fetishization of Blacks, Indians, Hispanics, Gays or whatever is a tactic to bring down the social structures of civilized societies by dividing their constituent peoples into warring factions. These societies can then be replaced with a marxist utopia ruled by the leftist elite.
“Fetishism” is a great word!
I take your comment to mean that this demographic has been weaponized and is now a tool of destruction of the left, just like black people have been weaponized and are now a tool of destruction of the left.
