I have an Asian parent, and the other is Caucasian. Some people think interracial marriage is a great way to prove you're not racist. That's a terrible reason to get married. Love is not racist, but sometimes marriages can be racist. Checkout this scene from Dragon: The Bruce Lee Story.
In that scene, the Caucasian guy likes Asian women, but he's a racist, and yells a racial slur at Bruce Lee, the Asian guy. Obviously not all mixed marriages involve racist guys, but there are some racist Western guys out there that are attracted to oriental ladies. So be careful who you choose.
