In the context of "education", the person, race or culture using such language or slang that deviates from properly used English is showing outwardly that they have little or no education. I am turned off as it is by what my gramma use to call "educated fools" posturing and blustering on the 6 oclock news and find it hard to swallow some of their bs . . . but when someone comes at me with ebonics and street slang, I am even more leary. To me, it's what the language itself represents, the culture, the anger, the lack of whatever . . .
I am the first one from my family to be born and raised in California. All my other family members are from the south, Alabama, where you were darn smart for having completed the 6th grade. When I hear some of my relatives talk, I cringe and associate their verbage with ignorance and an aversion to knowledge.
I think the Cos has made a valid point, but all races and cultures should take to heart what he said.
