Oh I agree that the US seems to be exporting its puritanical bent, which is not a good sign for the rest of the world. I don't see the advertisement as being bad--as a girl who finds other girls attractive I was pretty turned on by it to be honest. But the woman who stands on a soapbox inside of me was quietly raging about how they're exploiting homosexuality to sell a product.
Honestly, I should shut that woman up, because if they're exploiting homosexuality to sell a product, that means "the gayness" has reached a point where it's become more equal with heterosexuality--after all, heterosexual imagery has been used to sell products forever!
