She is absolutely right; the reason people are deemed to be physically beautiful (and, be honest, the word 'beautiful' is only really properly applied to physical appearance) is because they stand out in some way. If everybody looked like a supermodel, the word 'beautiful' would not even have come into existence.
The Dove adverts are crap as not everybody is beautiful. It is a rare thing. Prettiness is obviously more common, but beauty is rarer.
It is a very positive article- focus on other things than physical appearances because beauty fades.
All she is saying that most women are not beautiful, but, so what, men will love them anyway.
Don't know why she is getting criticised; it's actually a sensible and postive article.
