My husband and I don't plan to get foster kids and eventually adopt until I get out of school, but it has been in our long-term plan for awhile, so I do follow articles on adoption and foster care.
TheCSO and I do not care what color the child is (though we'd be happy to do things to help the kid feel attached to his or her culture), we care that the kid is nerdy. Because nerdy kids likely have a rough time in foster care* and because we're nerdy and nerdy kids like and understand us and vice-versa. If the kid has read some Asimov, that's instant bonding right there.
Anyway, I found this article about a black family that adopted a white little girl really interesting. The idea of transracial adoption hurting the kids makes me disinclined to do it, but the number of non-white kids that need homes inclines me again.
*Having grown up middle class in a wealthy area, the trip to a trendy mall store will be high on the agenda. It's a lot easier to be nerdy when you're dressed like the other kids.
