Hmmmm....we don't have many of any of those, some Asians.
However, do the "replacement Americans" somewhat monitor, or "moderate" the domestic savages?
No, but they are the prime targets of their crime. It was no accident that Michael Brown was roughing up some Indian-looking fellow when he stole the cigars in Ferguson; whites gave up running businesses anywhere near the welfare hives a long time ago.
NJ is liberal on all things but race; Michael Brown would stand out like a sore thumb in many areas in NJ. For a densely populated state with a proportional number of blacks to the national level, NJ has few racial incidents because nobody has any misconceptions about race. Affirmative action policies have ensured that often the cops involved with policing minorities are minorities themselves; rather than risk their jobs/pensions/freedom confronting them, white cops have “stood down” since the government (at various levels) wouldn’t support them in law enforcement efforts in minority areas. Now the residents just kill each other without interference, and anyone who can flees the area.
