If you read the whole article (it's long, I know), it identified that race was the greatest single variable for predicting homicide. It notes that once you conduct multivariate analysis it becomes clear that single motherhood is the actual greatest predictor of homicide and that black households are headed by single mothers at extraordinary rates.

E.g. nuclear families of any race? Very little homicide. Child of a single mother? Lots of homicide.

well said and likely.

Another thing is affirmative action policies really muddy socio-economic status as well. The academic ability would be wildly different for the kid of an engineer and the kid of a diversity consultant. However, they are likely to be in the same income level. Handing out college degrees does make anyone smarter or better behaved, but earning a college degree (if that can even be done these days) does demonstrates a level of intelligence, planning, and commitment.

If memory serves, single mothers have median IQs in the 80s-90s. Children of single mothers are also beaten or sexually abused at vastly greater rates than children of nuclear families.

It shouldn't surprise anyone that low IQ mothers are more likely to make dumb decisions and suck at parenting, and that low IQ boys who were victims of child abuse are much more likely to engage in violence.

Removing democrat policies of coddling will do it without bloodshed. The black family in the 50's was doing better than white families are now so the welfare and other race based laws to remove daddy and sabotage the black family did that to all families.

Need more nuclear family Asians. :p
