The problem with articles like these and the theories behind them is that it ignores the fact majority of White men are racial and/or hold certain values and cultures differences that don't align with Black women let alone a Black person which means income and class means nothing.
So the thought process that Black women can just as easily go out in droves into White men's arms is ludicrous and agenda-driven.
7 out of 10, the average White man more often than not, is choosing a White woman. Whether he's Liberal, Conservative, Hilbilly, middle class, wealthy, poor, college-educated, fat, in shape, nerdy, athletic jock, etc, etc.
