No I don't follow Danish news, I googled "irma ballet denmark" or similar, based on what you wrote, and found a description (I have good google-fu). I remember going to Irma when we lived in Denmark (in the 70s), but I don't think I knew about same-sex attraction let alone homophobia then. (I didn't feel I was exposed to much gender policing either, although I have faint memories of some other girls telling me "girls don't X" and my response being "I'm a girl and I'm doing X".)

It's sad, but probably inevitable, that the most positive mainstream reporting of the opposition to the ad is in terms of homophobia - at least that is becoming more of a recognised problem. Gender policing seems worse now, and it's unfortunate that growing awareness of GLBT people and their rights is treating lack of gender conformity as equivalent to same-sex attraction, as though the mainstream can only deal with one idea at a time.
