Taking into consideration the glaring contradictions in the supposition of your question, if I merely preferred blondes, brunettes or white women in general OF COURSE I would fuck Halle Berry or any of the others if I were being paid to. Because UNLIKE the example you cite with David Duke, I wouldn't be a sheer racist bigot. But EVEN with respect to that, certainly those types of people are as consistent as pogo sticks anyway because as racist and bigoted as they are that has NEVER stopped them from the do as I say not as I do notion when it suited them to fuck and rape black women.
We all should know the story behind a fairly racist acting Senator Strom Thurmond who held some of the most racist sentiments during his career all the while fucking and impregnating a black woman (I know, who knew).
Like I said before when it comes to porn (NOT PERSONAL LIFE) what does who you fuck have to do with some preference or attraction anyway?? In most cases these people are fucking strangers for whom they are just meeting or seeing for the first time in their lives.
You've unwittingly authored the prime example which undercuts your entire point. Asserting that a person who prefers whites in a personal life (a point fairly irrelevant to porn IMO) would choose to fuck horridly ugly white women over gorgeous black women using an utter racist to make the point. Well, isn't that the point? That one would have to be and utter racist to make that choice. Given the history of men like Duke....as racist as he is....it wouldn't even be clear that he would make choice to begin with.
I believe in the overwhelming majority of cases IN PORN where a chick refuses to work with blacks it's the product of some racism somewhere along the line. Whether it be in the form some person around them like Nikki Benz or Taylor Rain. Or they themselves are racist bigots.
Too many people in this thread are STILL comparing the perfectly logical personal preference with the scenario of fuck for pay. TWO, DIFFERENT THINGS....I'm not sure how that's not obvious.
You are right.
