There was a show almost ten years ago were a black comedian went to racist groups to live with them for a day or a week or so. It actually had surprisingly little drama, maybe helped change some minds. Obviously it wasn’t very successful as a show.

In one episode he was living with a couple who absolutely denied the Holocaust. Towards the end the guy and his girlfriend were going back and forth agreeing on how much they didn’t believe it happened, until the girl said something like “I don’t think it happened but you know… It should have”. The man seemed a little shocked by that. It ended with the comedian and the racist talking things out and it at least seemed the guy was in thought.
