When you said in your talk 'some battles have been won' which battles did you have in mind exactly? Because the battle for women to be judged by what they can do rather than how they look hasn't, that's for sure; a woman out there in the public eye is still judged by her appearance in a way that men aren't.
You seemed to be arguing that in the 70s the Miss World protest was necessary because people didn't 'get' the connection between objectification and discrimination against women whereas now we all know better. But we have a situation now where the objectification has got worse, and the pressures on women to look good are horrendous. Look at the rise of plastic surgery or the crippling heels that women wear regularly these days, or the way older women in the media are discriminated against.
Of course you are an exception in that you are actually allowed on the telly despite looking like a normal woman.... and I am very glad an exception is being made for you (& v much looking forward to watching the thing you have been filming recently) but for you, in that position, to be saying 'oh, actually this stuff doesn't really matter to me' came across as rather smug and 'I'm alright Jack'.
I think you need to look more closely at why there was a protest aimed at Miss World - it's not all the feminists getting together and saying 'What's the biggest problem facing women today? What one thing do we really want to end? I know, Miss World!' Feminist protests happen all the time and generally don't get much coverage (Hooters is in some ways a much more symbolic issue at the moment, are there protests, yes, do they get media coverage, no). A Miss World protest makes a deliberate reference to the earlier Miss World protest which is just about the most famous feminist protest ever in this country. As such, it has a number of advantages: 1. people can grasp it instantly 2. the media cover it 3. It is a very clear way of saying 'Actually these problems haven't gone away.'
