But now that you mention it, I do have to wonder why the perpetrators of both incidents, white and black, were so willing to play into outdated miscegenation stereotypes. Justin Timberlake, white boy, takin' what he wants from a black woman, isn't that nice and original. And Nicolette Sheridan might as well have said "Pleasure me, Mandingo!" to that ballplayer whose name escapes me.
That is pretty sick, but on the part of the performers---not the people who objected to the performance.
I think you have articulated an aspect I hadn't thought of, and it seems very credible to me.
