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 or being Asian. Nothing can be better than the other, people (like you apparently) that think one race or ethnicity stands above the other are kind of 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 racist.
