Wow Katherine. You have said a mouthful. Food for thought. Yes, I agree, the black experience is so varied and diverse, which is what I have preached to my now grown daughter and I think she finally gets it. One's personal experience is the qualifier.
As far as the CFP, contact the editor and express your thoughts; he is quite open as I have corresonded with him as I plan to contribute. It is really quite open so go for it. I am printing this page now as I type to look up some of these references you have posted.

Thanks,
