The thing a lot of reactionary trads don't realize is that the birth control pill probably saved America from Brazil tier Africanization during the last half century. Not just because it prevented unplanned pregnancies from more covert dalliances, but also because of it's well known effect of blunting women's attraction to highly masculine men. As you can see in almost any study done on the subject and common culture in general, most people, male and female rate black men as being significantly more masculine than white men when it comes to facial features, physique, depth of voice, etc. However, due to the large number of women on birth control, many still feel more comfortable with the medium masculinity of white men as their biological urge for peak masculinity has been blunted. This has allowed white to compete in what would otherwise be a very lopsided advantage for black men, aside from socioeconomic considerations. This is also why I believe liberal women are somewhat less likely to be into black men, as they are more diligent about following contraceptive measure like the pill.
