The bottom line is, blacks, in a general sense, cannot get their shit in order. Theirs is a culture of shit, best exemplified in the crapola hip hop/rap genre. It's like they strive to underwhelm and underperform in all ways.
But no one can state why, that we know the black brain is thousands of years less evolved than those of whites, Asians, etc.
To openly present this fact is to have yourself forever labelled racist.
Our technologies and sophistication are mostly too great a suggestion, even, to the average black.
For every intelligent and civilized black, there are 10,000 running amuck. Like irresponsible, untrained wild pets.
