They are just pointless generalisations, you get good and bad in every country/ethnic group and often all you have to go on is what you see on the TV. Take away all the make up, fake tans, plastic surgery, photoshopping and complimentary haircuts and women all over the world will not differ by too much, maybe if one nation appears to have 'hotter women' then they're just better at presenting themselves. I think the Brits are catching up with the Americans in terms of plastic surgery, facial work and fake tans when in the past the gulf was huge.
