“The black/white thing is a subset.”
True. There are several fault lines that are not good for peaceful coexistence.
Race is definitely one. Religion is another, somewhat related is culture (values), ethnicity not as much if they share values.
The fault line in Yugoslavia was mostly religion.
In the case of blacks vs white, (or black vs asians for that matter), the big fly in the ointment is the disparity in AVERAGE IQ.
It is my firm belief that two groups of people with significantly different AVERAGE IQ (About 1 standard deviation), AND whose members can be easily identified as belonging to one or the other group, will never be able to peacefully coexist together. It’s a sad reality, but it is a reality nonetheless.
An uncomfortable truth!
