So now, it would be better to do it the other way around.
Where there was segregation both groups were kept apart. Couldn't swim with them. Couldn't attend a concert with them.
Today police will still question white people who are in a minority neighborhood (if you look to well off or 'don't belong' they assume you are looking for drugs or prostitutes or possibly lost). See it on Cops all the time.
Why,of course. Current “wisdom”(barf) of the left has decreed that nothing minorities do is racist. They are inherently perfect and can do no wrong. Whites on the other hand are inherently evil. So much for a color blind society,whitey. We must do penance for our whiteness and maybe the coming utopia of Equalitaria will put us in comfortable concentration camps.
