Are these behavioral tendencies that you refer to suppressed or not genetically prevalent in individuals from the Caribbean or actual Africa?
Those people who immigrate here want nothing to do with America blacks.
I blame the left and their political use/enslavement of American blacks for their behavioral tendencies more than anything else.
As with many things in life, folks see what they wish to see and blind themselves to that which they prefer not to see. In any case, I was referring to some traits/behaviours that are seen in a subset of the population and not in the entire population.
And, by the way, whites and Asians also have a percentage of their populations who are lacking something (whether genetic or learned, who knows as of today) - just with a lower percentage of those populations.
In any case, believe as you wish.
