It's not a black thing. It's a poor/lower income thing. You really believe that poor blacks beat women significantly more than poor whites do? I've seen poor whites: some of them are the nastiest, scariest, most sadistic people that you can run into. Not to mention blacks are way more likely to be arrested and convicted than whites, which skews the statistics.
But let's assume for the sake of argument that blacks do statistically beat their women more than white men. It's still meaningless as a statistic by itself because it doesn't speak to all the black men that DON'T beat their women.
For example, let's say the world's adult male population is made up of only 1,000 black men and 1,000 white men. Let's say, 2 black men beat women in 2014. Let's say only 1 white man beat a woman that year. ZOMG, black men beat women twice as much as white men! Uh, ok, but um, there were still 998 black men who didn't lay a hand on women. Total fearmongering.
Statistics. Not even once.
