Hello,
Sources please! Even though If you had any I would disprove them out of sheer common sense.
I dislike your attitude. You cannot disprove scientific research simply because you don't like it, you actually have to conduct the same experiment with a different sample and produce conflicting results, or conduct another experiment to challenge the foundations of the study. Your sheer "common sense" accounts for absolutely nothing in the scientific world.
For everyone interested in racial differences in testosterone levels, I can tell you a bit about it. When considering simple free testosterone levels, research is conflicting. Some studies find significant differences, others do not. However, simple free testosterone is merely the amount of testosterone that is floating freely through your blood and not actually being used. Testosterone binds to SHBG (sex-hormone binding globulin). Whilst research is conflicting regarding racial differences in free testosterone, it is consistent in finding racial differences in SHBG. African americans typically have around 25% more SHBG than caucasion americans. This means that they are more able to make use of their free testosterone. In other words, there most certainly IS a biological racial difference relating to testosterone, though it is not as clear-cut as simple blood hormone levels.

Despite what popular culture and "common sense" may tell you, there most certainly are a wide variety of very real biological (ie: genetic) differences between races. The differences are not only in the colour of our skin and our height. It is not racist to acknowledge scientifically factual differences, and to call someone racist simply because they are noting such differences is simply stupid. It's exactly as stupid as calling everyone here sexist because we acknowledge the difference between males and females. There are many, many people, both male and female, who would claim that there are no gender differences beyond our genitals. Who is more stupid? Those who blindly attempt to claim pure inherent equality for fear of prejudice, or those who acknowledge the differences inherent in different groups of people, either as a function of race, gender, culture, religion, etc?

As to the post topic, I would agree that more white women are attracted to black men and black men attracted to white women, than white men are attracted to black women and black women attracted to white men. There's a reason for this: in nearly every culture in the world men are more attracted to girls with lighter skin, and girls are more attracted to men with darker skin. The difference in shade doesn't have to be huge, as in between whites and blacks, but more often can be slight, as in the difference between a tanned person and a pale person. The reason is complex and related to genetic fitness, because skin tone is correlated with certain sex hormones, which in turn determine physical health and propensity for diseases. Lighter skin on females indicates better physical health and better genes, and for males, darker skin indicates these qualities. These differences occur
within races, not across races, so it doesn't mean that white men are sickly and black women are prone to disease, nor that white women and black men are invulnerable to health problems. But it does mean that among a given race like caucasions, paler women have better genes and are more feminine, and darker skinned men have better genes and are more masculine.
I could go into a lot more detail but it's unecessary. The point is that genetically speaking, it makes sense that females of any race will be more attracted to darker skinned males, and vice versa.
