Thanks for all the considered responses to the programme. These would be so different on the male-dominated forums I am used to - not that the ones I visit most are discussing the programme, as I suspect most men wouldn't have watched it.
Yes, perhaps only racists would have had their dislike of Chinese increased by the programme, but IMHO the boundary between racists and non-racists is not clear-cut. Few people are irremediably racist but I suspect that no one is entirely immune to racist influences throughout their lives. It may be only too easy for dislike for the way individuals of a particular "race" behave, to turn into a blanket racist denigration of that race as a whole - such as the rock-singer Morrissey describing Chinese as a "sub-species" because he didn't like the way some people were mistreating animals in China.
Thus programmes such as the one we are discussing, with its biased production and editing, could have influences on particular people in their perception of people of another race - could indeed sow the seeds of racist dislike and hatred.
Incidentally, British mums need have no fear that the programme would make them feel inadequate - rather they could be left with a feeling of effortless superiority over these crazy Chinese tiger mothers. Is it a coincidence that the most sympathetic character portrayed was the white husband of one of the women?
I may be being over-sensitive, but if so, I hope you will forgive me in my circumstances, which I could detail if anyone is interested. Actually, I am culturally almost totally British, and regard myself as British of Chinese ethnicity. I think the UK is still an admirable country, and wouldn't prefer to live anywhere else. I believe that the British people in general are among the most civilised and tolerant in the world, but there is a large and significant minority who are highly xenophobic. This is not confined to the BNP types, but includes many who read such papers as the Daily Mail and Daily Express.
