What traits are you referring to? What is it you notice?
I havent read over this whole thread so if you mentioned it previously my bad.
Everything from believing that children are blessing, God told us to replenish the earth, so called "good" hair, the mack, the diva, the thug, the buck, even thing that were originally positive traits such as the slick and cunning slave who found clever ways to manipulate the slave institution to get out of slave labor has morphed into distrust of authority, teachers, parents and even doctors. This is the same driving force behind bullshitters who cant hold a job or follow laws. Its responsible for us hating ourselves and other blacks because slavery disjointed our perception of what it means to be a black man.
I can go on and on but typing on my tablet at work sucks, but if you really want me to go deep, I'd do it when I have more time.
