I'd bet most of those Bisexuals and Lesbians are straight, a huge swath of the 'trans' are actually gays and lesbians (Butch Lesbians = told their men, Camp Gays = told their women), and many of the 'gays' are actual Bisexuals who are identifying as gay for social value since Bisexuality doesn't score you much in the way of social points, but you can prove that you like dick unlike the straight guys who just say they are gay.
It's obviously a social contagion.
