Do not worry about trying to please everyone. Ther will be for sure people who will not like the interracial theme, period. Or it may be snuff, or young characters, or anal action, who cares? That is why you can put tags on your story when you post it. Only those who can not tell the difference between fiction and fact will feel insulted. If you can make your character interesting and sexy, I would not personally care if he is black, yellow or fuschia.
