Here’s the thing - if a woman wins Mastermind or leads the winning team on University Challenge, that’s admirable, because she has proven intellect, and applied herself to mastering a subject.
If a woman wins a beauty competition, she has not really achieved anything, because her beauty has nothing to do with her. It’s all about her genes, plus the skills of the hair and make-up people.
Let’s put it this way - if you had a 12 year old daughter and you asked her what she wanted to be as an adult, you’d feel proud if she said, doctor, engineer, teacher or scientist. I think most parents would feel less proud if she answered, “Pretty, with a 36-22-34 figure”.
