Guys reveal a lot about themselves with their online dating profiles, especially if they're allowed to show the world what kind of men they find desirable.
Take the profiles on bigmuscle.com and its many spin-offs. Any member can click on any other profile and let people know: I like this one!
Many guys have hundreds of favorites but zero who are black. How do I know this? It's easy. All I have to do is tell my computer to search a person's favorites and highlight BLK or BLACK, two things commonly found in screen names created by black men.
It's all online for anyone to witness and quantify: most gay men can pick out hundreds of men they like without having one single black guy on the list. How is that possible, unless they already know what studies have shown: Black Gay Men are Least Wanted.
