My sons will learn about their polish side as much as they will learn about their Cantonese side. I don't think being mixed is better than being white but it is better than just being Asian. Anything can be better than being Asian, people (like you and me apparently) that think one race or ethnicity stands above the other aren't the problem here to be honest. "The less white people the better"? If that's the way you think okay, but that to me sounds stupid.
