I don't think that the issue is that Americans find the skinny jeans to be a 'gay' look. I personally object to them because they are part of some sort of weird hipster-goth-Twilight androgynous look. They are popular with men and women who are, generally: thin, pale, medium-long hair, black nail polish, wear V-neck t-shirts as outerwear, Army-Navy surplus coats or the Gucci version of such, Converse sneakers, and stuff with The Ramones. I find hipsters objectionable.
