Issa Ray's facial expressions were an illustration of the perils of going on this show - that you might find out your ancestors are people you really wouldn't want to associate with. Her relatives being slave traders and then dying in the Haiti slave uprising looked really upsetting to her.
The show last night was one of the few I've seen with all white people. Pelosi, O'Donnell, and Posen. They seemed to focus on more recent history rather than tracing them back to villages in the 1600s.
