Its one of their favorite activities, or so it would seem. There is too much machismo in their culture. You will often hear them screaming the word "disrespect" at each other, because they resort to primal behavior. They all vie for dominance and can't stand being shown up, so they go and seek violent vengence.
Their whole culture is predicated on the "show em whatcha got" idea as well. they don't invest money, they show it. Rims, jewelry, clothes, stereo systems, tv's... all expensive items that others will notice because, like their primate relatives, these are shows of dominance, constantly trying to one up each other. God forbid they save their money, invest it wisely and stop caring what other people think.
Black culture spews out violence ridden rap and hip hop. Artists, geniuses, like stevie wonder and marvin gaye preached peace and love and harmony back in the day. All the popular rappers today rap about the streets and clubbing. Almost every black kids dream is to sell drugs and make it as a rapper. Anyone who says anything truthful about blacks is labeled a racist or an elitist (like bill cosby).
And the main problem is that black men are cowards and won't take care of their babies after they knock a bitch up. They all run away, leaving the kid to fend for itself, learning from the wrong people in the wrong places and the cycle repeats itself.
