Of course beauty is in the eyes of the beholder. The question was not "Should there be more supermodels?" Personally I would be very happy if the (to me) obnoxious and tawdry fashion industry vanished today. That does not make me wish to make spiteful remarks about the women who earn money out of it.
I will take your word for it that anorexia is ghastly. However - and this is also the view of many feminist and health writers - overeating and lack of exercise actually harm far more people. A whole industry is based on persuading people that it is a good idea to consume more fat, sugar and additives.
I also think it would have been a good idea to put the first sentence of my final paragraph into context with the two sentences which followed it. I am most surprised that it has given offence.
