Let me make it absolutely clear, because earlier replies to my comments seem to indicate that I am accusing the jury and defense of being racists. I AM NOT ACCUSING THEM OF RACISM. What I am saying is that the defense IS actively painting a picture of Trayvon as a "menacing black youth" to more effectively convince the jury of a 'propensity' for violence. It is overwhelmingly composed of suburban mothers and the most effective way of counteracting their instinctive sympathy as mothers is by painting an image of Trayvon as "that kind of black kid", the one that single women driving through the city at night lock their car doors when passing. The defense attorney is doing his job. I find it nauseating, but that's what his job is: to take advantage of anything he can use to cause the jury to doubt witnesses for the prosecution (and more so when helped by bungling witnesses like Ms. Jeantel) and tell the narrative he wants to tell. I do believe it has a racial component to it because there is no cultural shorthand for crime that is as potent as the threat (implicit or explicit) of black male violence in the modern media and the average white mind. There simply is no white corollary with the same widespread cultural acceptance. Labeling someone as "White trash" simply does not provide as powerful a set of accepted images, nor convey the same threat in the mass mind, and even more so in the white mind (obviously I'm speaking in general, not every single white person in the nation).
I'm not saying this is what Tray meant if/when he used the term, but I have to tell you that 'Cracker' in Florida is a non-racist phrase used in FL to refer to non-foreign born whites who have lived in the state for generations. Whites in FL call themselves 'Florida Crackers' the same way Indianans call themselves 'Indiana Hoosiers' - which is itself a pejorative in the rest of the midwest. It comes from them 'cracking' their whips during cattle drives south through the center of the state. True story.
