Well the fact is, gay men do play a major role in the fashion industry, that's undeniable. And many runway models have to have very masculine looking bodies in order to model clothes. Tall with a bad hip to waist ratio. These models certainly aren't women that look like that cute "girl next door". Sometimes they look like men in drag.bigjohnson said:"Anything I don't agree with has it's roots in the <insert negative origin theory>"
Being fat was only "attractive" at certain points in history, and that was because fat meant prosperity. In recent history there has been a lot of emphasis of fitness and health from a scientific standpoint, and it's influenced our ideals. On that tangent, if you want to see a sub-culture that's heavily influenced by homosexuals have a look at the local gym culture.
And then you look at the male models, and rarely do they look masculine in the Clint Eastwood sense. They tend to look boyish and gay. That whole "pretty boy" with the six pack look you see in Calvin Klein models.
