I base this entirely on my personal experience. Others may disagree with me, but for whatever reason...blondes just have it out for me. I've gotten nothing but grief, heartbreak and abuse from them. I do not have a remotely positive experience with any of the blondes I've dated.
I've always had much better luck with brunettes. I find blondes tend to be much higher maintence as well...although all women are high maintence to an extent.
So, I've come to the inescapable conclusion that I should never date blondes again. But, since I'm engaged to be married I should never have to make that decision.
I had never heard those stereotypes about black and chinese women.
