There are two things I like about this particular example of adoption.
1) While celebrity interracial/multiethnic adoptions tend to focus their attention abroad, adopting children from third world countries, Sandra has adopted a black child from New Orleans. This says a lot. Throughout the course of the semester I noticed a trend in American adoptions. American adoptive parents tended to adopt black children who were not from America. I thought this was interesting, because if you want to "save the world" you would think that at least some parents would want to start close to home. However, I think that adopting black American children sent a message not many people were willing to send. It was better to adopt a black child from an impoverished country.
But Sandra has set a different example. I am happy for her and feel that she is doing this for the right reasons, for the love of the child and not for the public message. That's brave.
2) Sandra kept this "on the down low" for a while, which to me reinforces the impression that she wasn't doing this for publicity.
Good for her!
