As Obama has taught us, they should call themselves black.
Does anyone remember Tiger getting crap because he was "denying" his blackness?
Biracial kids (black and white) are considered black. It isn't what Obama taught us, if you look back through American history, you will see that you were considered black until you were more than 1/8 or 1/16th black.
Anyway, I think this is stupid. I don't think whites need training on adopting a child to love. I can see a point where they might want to make sure the kids are culturally aware, but honestly, out of the few white couples who have black or biracial children, they are already quite aware, and teach lots of history to their kids.
