I saw that last night too, just caught the end so got that question. Almost everyone is talking about it as sex discrimination, so even though the BBC won that point at the tribunal, they've lost the public opinion argument. James Caan was being a total tit about it, "consumerism" - yes dear, is all you can say to that.
Mind you I had woman's hour on this morning (when will I learn??) and they were talking abour Carmen. Some opera bloke (director I think) was saying "everyone finds strong/beautiful/intelligent women a turn on" or something v similar. Well, I don't. Because I'm a straight woman. I doubt any of my gay male friends do either FOR GODS SAKE. Straight men rule to the extent that we all have to find the things sexy that they find sexy now? Might seem off topic but it seemed to chime with this idea that "the consumer" or "everyone" wants to see young attractive women (but not men, apparently).
