I see this brought a lot in BP about how they think its not right that a guy only likes Asian girls.

Personally, in my experience I have been with men of all races, but only black men have really satisfied me. There is just something about them, how fit, robust and strong they are, both mentally and physically that blows me away. All of them just seem so confident and the way they carry themselves, its like I know there a real man when I see them.

Are thoughts like these inherently racist? Or is it just sexual preference? This applies for either gender.
