Isn't he just describing a preference? (I can't open the link on my phone for some reason).
If he is, I don't really understand the vitriol. I don't agree with him - I think Liz Hurley, at 53, is the sexiest woman on the planet - but if younger women are his preference, then so what.
Ever since I became interested in women I've always had a 'type', and therefore I think these things are hard-wired. My preference has always been slim and brown-haired. I can objectively see that some blondes (for instance) and larger ladies are attractive, but because of my type, I've never been attracted to them.
