I saw something on Oprah about this. One part that I remember is that the black guy who was turend white was working in a bar in a very white neighborhood. He said it was very interesting for him, because he knew there was NO WAY people would have been that open about thier thoughts on race had they known he was really black. One guy made a comment about how they didn't want "them" moving in thier neighborhood because it had always been like this, meaning always been a white neighborhood. The white guy thatw as turned black was participating in a focus group or something, and thought he'd toss out the "n" word, and found out it doesn't work exatly like he thought it would. Overall they all learned a lot about the other race and have a new respect, at least from what I saw. This is one of the few reality shows I've ever considered watching.
