Thinking about all the white nerds on TV, movies, etc. I don't recall any female characters coming around to wanting them. If they have girlfriends its usually their fellow geeks.
In fact, the only time a nerd had a girl eventually come around to wanting them was black (Laura Winslow and Steve Urkel). But to be fair, Steve was more than just a nerd. He was an obsessed stalker who was a walking accident waiting to happen. The Winslow family must have paid thousands of dollars to repair all their furniture, windows, roofs, front door, etc.
Me and all my friends had a crush on Steve Urkel actually :smt003 Although we leaned more toward to his 'alter ego' Stefan Urquelle.
Remember the character Myra who was in love with Steve and his girlfriend for a period of time? So there you go.
And if I remember right, even Carlton had a few women of his own. Jackie played by Tyra Banks (before Will came in) Lark Voorhies who he was going to marry, that girl in the tight American flag dress, and that woman who took his virginity (although she ended up being married). I can't believe I remember all of this on the top of my head, lol.
Women loooooove complaining and going on television to do so, and will talk about it for anyone who will listen (especially if it has to do with their romance woe). Men don't do that. Race has nothing to do with it.
