I know...I get it from my daddy...[g]
When I first heard of ebonics, I asked my wife (an ESL teacher) how wide the window was for teaching someone English so they would speak it without a "foreign" accent. The answer: after about ten years old, a "second language" speaker would have to do a LOT of vocal training (none of it cheap) to get rid of an undesired accent.
"Ebonics" is child abuse. The Klan must be laughing up the sleeves of their robes over this: those taught in ebonics are going to mark themselves as lower-class citizens the instant they open their mouths.
