No I didn't. Because it's not just blacks who "amalgamate" along racial/ethnic lines as gangs. Step into any prison and you'll soon become acquainted with the social arrangement of things, and not picking a side is not an option. And out on the street it's the same - white gangs (bikers, usually), black gangs, mexican gangs, vietnamese gangs. It goes back a long way ... italian mafia, KKK, etc. They do this because of some base and misguided instinct humans have of trusting "our own" more than "the others."
I would appreciate if you would refrain from attempting to be Chris Matthews, suggesting secret racist implications in the words of others in an attempt to score a few points. I'm trying to neutrally and honestly discuss race to the extent it may be a factor in influencing the extent to which people may be willing to 'look the other way' for Obama. It was being discussed in this thread already, and I ran across an article that was on-point and current, so I linked it. I also noted that it appeared to me the substantive content in the article did indeed support the conclusion that Obama being black does have an effect on the black community's level of support for him. The opinion content at the end of the article seems intended to defuse that.
