I have one more thing to add to this thread. I am trying not to beat a dead horse, but this point is bugging me, so here goes nothing:
John, I think if you had come to the board BEFORE finishing your project and said, "Hey I'm thinking about writing a book with mainly African American characters, etc...and I'm white...how do you think Black readers will react to this...etc..." then it would have been easier for me to accept your motives as sincere. Under that scenario, logically, it would have made sense to come to a board like this. Indeed it would be wise to do so...get some feedback, show you care about what your potential audience will think...get some constructive suggestions about how to respectfully handle your characters & portrayal of historical events.
But since you already wrote the book, published the book, and started selling the book, and THEN you came looking for feedback, it makes me think you are simply trying a new marketing strategy. I have no problem with you marketing your material. But don't insult me by acting like you're just curious to see my reaction to your color. Be real about the situation. If you're coming to the board to broaden the exposure of your book, then just say that: "Hey, I wrote a book about Black characters...here's the synopsis...check it out..." And if you feel you must include the fact that you are white, then say that too..."oh, by the way, I'm white...do you care?"
I could respect that.
