Maggiemaybe I'm fairly sure I watched that documentary. The young people who took part, including Stacey Dooley, were not, I believe, journalists but just ordinary young people. I didn't mean "reality" in the sense of Big Brother but that it was ordinary people, not professional journalists, responding to the situation they found themselves in.
I find it odd that Lammy is being accused of racism for just expressing an opinion, whether you agree with it or not, about the way in which African and white people are portrayed. My own feeling is that many of the comments on here have far more racist undertones.
