Do you think having a bi-racial child is putting your child at a disadvantage?

I have dated a variety of men and although my typical type is blonde hair blue eyes I have never limited myself to a particular type because I do not feel that the outside really matters. We all become ugly and wrinkly right? so who really cares? Anyways back to my question: My mom disproves of me dating outside of my race and her rational is that if you decide to one day have children who are mixed they will be socially disadvantaged ,will not idenify with a race and will be teased. I tend to disagree with her, thinking (and hoping) that it is not that big of an issue today. I am not however, not biracial so I cannot ert an argument out of my own personal experience. So just curious one everyones thoughts,particularly if you are biracial
