let's say that I become good friends with some people of that race. Then, I will see that they are like me, and I will start to find some people of that race attractive too. You suggest that the primary reason you wouldn't be attracted to someone of a race is because you aren't "good friends" with anyone of that race. In my experience, that is false. For example, I know quite a few Asian girls who prefer dating white guys over Asian guys -- would you suggest they "aren't good friends" with any Asians, or that they are subconsciously racist toward Asians? Different people have different preferences for what they are attracted to; in many cases, those preferences will be correlated with race (e.g. if a girl likes tall men with dark features and olive skin, she is less likely to fall for a 5'5" Norwegian). That's not racism, that's just human nature.
