Language is supposed to communicate a message in a clear manner. Proper grammar and syntax use will insure that the message will be understood by all people educated in that language.
I wonder if it has ever dawned on these illiterates that much of their problem is an inability to articulate their message. It has nothing to do with race. It has to do with culture.
And how racist is it to expect that the white people have the natural capacity to be bilingual, and the non-whites are not.
When I hear blacks speak standard American English my respect for them goes up 10 times.
