You are incorrect in attributing this to an ethnicity. This is a cultural issue. Rednecks from heavy meth zones present the same lack of skills. I understand the disgust and anger, but refocus. It's a cultural (and to the religious, spiritual) war, not an ethnic problem.

In fact, attributing it to an ethnicity allows the true problems to be neglected under the shield of racism.

Now, biologically, both of the example demographics do often present low functioning intelligence in children, but this is a nurture issue related to poor parenting/neglect and very frequently, drug/alcohol use while pregnant. It is the tolerance, acceptance and praise of this type of culture that is problematic.

And I will tell you, as a Yankee that moved deep South, there are parts of the country where drug abusing redneck is just as culturally hot as inner city street criminal. In fact, I've lived in places where those were the primary two breeding demographics in males, no matter the cultural background of the females, and has been for generations.

You know what you get? People of all colors, living like animals. And proud to be. And every single mom wondering why daddy didn't stay, why he couldn't stay out of prison, why every man they date beats them, etc etc. Anything to not look in the mirror and realize it's that they're choosing animals. The conditioning is that strong, they can't even begin to comprehend their own lives.

It's a problem that's so far beyond the focus you are giving to it. It's a cultural structure on the brink of collapse.
