White and Asian mixed women are some of the most racist people you can find. You would hardly be able to shake the hand that alone date of procreate with one. Of course this has been my own personal experience.
There's racist people in every group. It means nothing if you got more to offer than other men.
People that state they have a racial preference when it comes to dating are typically not desirable. They do this to get brownie points from the people they are trying to attract. If you are a desirable person then you want the best mate possible and that best person can come from any group.
