It was an interesting programme to me, if not perfect by any means.
What was perhaps most telling is some that folks felt so uncomfortable and defensive about the whole idea, a belief that somehow they didn't need this learning. There's often a tacit acceptance that Britain is fairly sorted when it comes to racism, especially compared next to the more confrontational USA, but the urge to sweep things under the carpet and be more dismissive about the possibility that racism still seriously affects lives here is far more palpable.
I think that was the most valuable thing to come out of the programme. Not what it set out to achieve, but very informative nonetheless.
