There's a lot of "racism" crybabies on this forum.
Honestly, I personally have no problems with racism as long as it does not interfere with undue influence in what is supposed to be a "fair" situation.
I will date yellows and whites, but I do not find blacks attractive. I'm yellow. I have no problems with any race, period, and I am more likely to react negatively to someone's attire, posture, behavior and cleanliness.
So what if the guy is racist when it comes to his love life? Why does it freaking matter? I know we're not all bleeding heart liberals here, and I definitely do not see what the big deal is with him. He's entitled to what he likes and doesn't like when it comes to romantic feelings, and if he does not like chicks that date black men, that is his prerogative. If I can trust him on his word, then we can assume that in any other way, the guy is not racist.
To stand on your little pedestal and belittle him because he's making a personal choice that you don't like is ridiculous. There is more you can do to help him analyze his feelings and ideas other than to be exactly what you are trying not to be - a polarized, narrow minded fool who's thoughts and actions are so entrenched in habit that you cannot change them.
If he isn't hurting anyone, then there is nothing wrong. Not everyone has to subscribe to your view of reality, and your attempt to impose that on the OP is wrong.
