What is making these Black students feel uncomfortable is that they have been brainwashed. Blacks for generations have been brainwashed to believe that white racism is the cause every affliction in their community. Drug and gang culture, soaring no father families, disdain for education etc. are all afflicted on them from a white majority and they have no responsibility for these things and are solely victims. This brainwashing is perpetuated by race hustlers like Sharpton and liberal politicians like Obama who benefit from Blacks knowing their place in the liberal plantation and voting as a block for Democrats who will protect them.
Rachel Jeantel and Trayvon Martin are the products of this liberal plantation culture. They fail in school, but that is the fault of the white run system, not their own apathy toward learning. Using proper English, wanting to go to college, getting good grades is denigrated as acting white and betraying their race. They immerse themselves in a destructive gang and gangsta culture, where rap stars, drugs dealers and pimps are role models for success. No wonder Black feel out of place in a normal society.
Remember the "In Living Color" sketch "Hey Mon!".....It was about a Jamaican family all who work three or four jobs, and think that anyone who only has one job is a "lazy lima bean." At least that's how the blacks in Britain used to be, until our hip-hop culture crossed the Atlantic and poisoned them.
