"I've had black friends be told by other blacks that they weren't normal because they weren't speaking to each other the way normal black people are supposed to."
"Code switching" is the term for what I was taught in my first sales job. I had (and still can have, if it's advantageous or to make friends and family comfortable) quite a southern Appalachian twang. Learning to deal with the larger world on the terms of that larger world is not selling out, unless you are so uncomfortable with your own origins that you want to shed any evidence of those origins completely. I don't, and haven't. I can't help but think that my own experience can be applied here.
