Well....When you put kids in a situation where losing a fight causes your parents to ridicule you, it’s easy to lose hope. They encourage you to fight and then call you a punk if you don’t stomp the other kid into a greasy spot.
We have a sub-nation of feral, violent animals and it transcends race. These hillbillies up here are the same way. We had to close the Denny’s here because of it. Cops have to come to the funeral home to prevent brawls between redneck families.
There are two kinds of DNA in human society. One is biological and humans can do little about it (for the most part). The other is the DNA of culture, and it is sometimes passed down with as much strength as the biological DNA. But there are cures for the cultural DNA, and one of those is for parents who see it as the problem to move, to keep it from being passed to their offspring.
