Suppose you are the last person to get on a train before it reaches capacity. You are more likely to interact with someone who is on the same train than someone who isn't. If you prefer to interact with people of the same race, you would be better off if your train had been restricted to only people of your race. Similar logic applies to a full bar or any workplace. If you prefer to date people of a certain race, you also prefer to interact with people of that race compared to others of your desired gender since less intimate interactions are a prerequisite for dating. "It would be nice if everyone was so enlightened as to not care about race, but there is 10,000+ years of evolutionary pressure pushing things the other direction." No such pressure exists. Cross-breeding is usually evolutionarily advantageous. http://en.wikipedia.org/wiki/Hybrid_vigor http://en.wikipedia.org/wiki/Hybrid_vigor "There are 5.9999 billion other people the person you discriminated against can date." The same exact logic applies to jobs. Sure, the job you get may not pay as much or might not be in the location you would prefer, but the mate you end up with might not make as much money or be nearby either. Eliminating potential mates from consideration based on their race is just as bad as throwing out the resumes of an entire race because you think they're not likely to be qualified for the job. It does hurt people. Mating is a market just like everything else in life, and if you reduce demand for someone's product due to something as arbitrary as melanin level, then you're reducing their equilibrium price and requiring them to make more compromises when it comes to choosing a mate. No one expects you to sleep with someone just to give them a helping hand, but that shouldn't be expected with jobs either.
