Wow good topic.
I myself am mixed due to my grandparents being in a interracial marriage. Both my mom and dad are in interracial relationships.
Though the first time I saw something negative come to it, is what happened to a freind of mine. My freind is black and the girl that he was hooked up with was Asian. This was a big problem with her parents because they wanted her to be with an asian man OR a causasian man. African American and Hispanic was OUT as far as they were concerned. It was sad listening to my freind telling me this.
