This is a race to see if the unassimilated minorities can destroy each other before they focus on whites; here in NJ one consequence of open borders is that the worst ghetto cores are surrounded by ever-widening rings of brown and yellow people that further separate blacks from whites.
Looks like the same dynamic is at work in Ferguson MO, when Michael Brown was pushing around a little Asian guy...
Made me think of the Rwandan genocide when one day local radio started screaming for the Hutu to kill the Tutsi; and they did.
“The genocide was planned by members of the core political elite, many of whom occupied positions at top levels of the national government.” (Source Wikipedia)
