The "culture" of blacks is the same as poor Southern rednecks a century or so ago, as Sowell argues. Mandatory school is an imposition they are being forced into and they fucking hate it. As to the fighting, its an honor culture where even the slightest sign of disrespect must be met with violence to save face. Not that this excuses anything, but it's a huge reason why black inner city schools can't be fixed with more money. I'd guess 90% or more have no fathers at home and were raised by their friends on the streets.
