I live in South Jawja and I didn't make note of the incredibly insensitive use of the word "boy" for young man.
That said, I can assure you that the yoot named De'Marquis is black.
As an aside, there are many fine young black men down here raised in fine Christian homes...so it isn't a racial thing. It's a cultural thing...it's that I hate America and I hate Whitey thing that Obama is so fond of.
Blacks are the most murderous group in the US. To say it's cultural rather than racial is a distinction without a difference.
