Its part of the cultural problem we have. Young men are no longer encouraged to be smart, because it makes them "non-urban". This desire to be "urban" has engulfed the male population of all ethnic groups and races. "Urbanity" can be described as thug-like behaviour, combined with ignorance. As the comedian Chris Rock says in his comedy routing "Bigger and Blacker" (I believe), one of the things he hates most about n*ggaz, is that "N*ggaz love 'not to know'. You ask them a question, and they says 'hell, I dunno'".. Substitute "urban" for n*gga and you get the picture, since this urbanity crosses all color lines.
While the same might be said for females, this is not the case. A woman today can still be "cool" by being smart AND sexy. So we have bright girls today showing their midriffs, exposing their tatoos and navel piercings. But it is OK, if not preferred, to be educated for them.
you should see Chris Rock live, the audiance is almost as entertaining as he is.
He was basically trashing a large portion of the audiance (which is usually more than half white) and the people he is trashing relentlessly are to stupid to know it.
