What bearing does Trayvon Martin's criminal history (or lack thereof) have to do with this case?

33. But you aren't answering his question...

This guy could very well be a racist, but that really isn't the point. He raises an interesting question, "Would you want to live in an all-black environment?" Of course, the fact that the black population of the United States has suffered the most from the ridiculous income gap that plagues the nation, plays a major role in my answer.
No, I would not want to live in an American all-black environment, not because of the color of their skin but because of the rather cruel environment that has formed the basis of their experiences. And of course, each and every black person does NOT develop into an unsavory character due to being subjected to the plight of the low-income class. And of course, not each and every black person who is raised in a comfortable income bracket becomes a well-mannered, good person. However, the economic environment in which one is raised does play a major role in the personal development of all races. This truth may sting like morning light through sleepy eyes, but failing to address the problem will only result in a progressively deteriorating situation.
As the wealthy elite continue to hoard their gold and determine the US's future through campaign contributions and lobbying, and the 99% are denied the right to assemble peacefully as stated clearly in the Constitution of the United States of America, prepare for gloomier days ahead.
