Why can't you be nice to a white girl without having her think you want her?

I'm not going to make racial umptions but I agree on this. Girls I've dated or tried...the ones who act like this are white (as in American). Not saying that all of them are like that, just the ones that do are mostly white. I stay away from this type, high maintainance and will result in a fake, superficial relationship. Let's go find those nice, genuine girls.
