When you get right down to it, most people... especially most black people, know good and damned well how incredibly believable it is that Trayvon was immersed in that thug culture, they know how common that is among black youth.
They see his social media and they see how he dressed, how he posed for pictures, what he tweeted... they hear about the bag of jewelry, and they know god damned well what sort of person he was.
Because of this, they know that the version of events GZ lays out is not just possible, not just probable, not just believable... but the truth or damned near to it.
They simply don't care. They're deluding themselves and hoping to do the same to others because they care more about being anti-gun, making sure they're not RACIST, and keeping their head firmly buried in the sand regarding the realities of race and culture in our country, than they could ever care about the truth or law.
And there are a lot of black people in this country who know Trayvon was almost certainly the aggressor, they know how kids like that think... they just don't give a fuck. He's black, so are they, end of story. "My race, right or wrong" is the mentality. It was on full display with OJ as well. Even the child molesting Michael Jackson got a pass, because he had once kind of been sort of black.
It's disgusting, morality takes a back seat to race. No doubt at all who the most racist group in the US is in 2012, but they get a full and free pass because white people sliced their own balls off some time ago.
