That's some bullsh!t. I strongly prefer Hispanic or black women, and I like certain Asian women too. I don't like white girls that much due to some bad experiences with them when I was younger.
Anecdotes =! stats. Im not sure of the results of the study but post a separate study that can prove why its not real.
Regardless, I think it's more of a societal thing than a natural thing. many older people are still raising their kids to think that dating outside their race is wrong, as well as the tendency of many people to live in areas that are full of people that resemble them.
