Acceptance of Urban Feralism, white “go-go areas” ad nauseam - this is de facto deconstruction of teh Republic into race based rtibal areas.
If this is what you want, might I suggest South Africa?
There are parts of town you don't go into. They went there. That doesn't mean they deserved a beating, but you need to be aware of where you are.
If you honestly believe that you can go anywhere you want to and not expect a challenge and or attack, you are a fool. Go walking at night in the Ford City part of Chicago. Let me know how well that works.
The cops won't do anything. If they did, you would have a riot, lawsuits, and the NAACP attacking you in the courts. So the de facto result is containment.
It is the unspoken rule in many areas.
If you travel a lot, be aware of where you are. If you are local, then you had better know what places to go, and how to get the heck out of the "bad" places. In certain places, you don't go to anything "free" (like where I live) as you are pretty much guaranteed that there will be at least an assault if not a shooting or two.
