Are blond girls always hotter?

Okay, most of my friends are either natural or fake blonds. They get lots of dates/people asking them out, etc.! Not to brag, but I'm just as pretty, taller, and thinner. I have reddish brown hair, blue eyes, and pale skin. They're all blond, tan, and have brown or blue eyes.

It seems like in the USA our idea of beauty is blond?
Guys, do you like blonds, brunettes, redheads, black hair, or what? It seems like all the guys I know only date blond girls (how superficial is that?)
