I have a feeling that one girl who reacted negatively who said. "Its so weird to say you only date..." I"m willing to bet she only dated white guys, and probably will always date white dudes, but won't ever conciously admit or acknowledge it. All the ex did was point out the Bachelor a TV show only has white bachelors, and then they had a token hispanic. (Although lets not kid ourselves Juan Pablo was white, and ABC just dubbed him a "Hispanic/Latino" to try, and be PC. Not acknowledging that white Latino's exist is a denial of race, and reality.) In short TMZ did the classic trick of putting the focus on her individual preference for black men rather than the problem of that a TV show exclusively casts white men for leading roles.
Or maybe it was deemed something to be a topic too intellectually stimulating for a program like TMZ.
