Being gay is a fetish.

If there's anyone who's actually interested in research, here's a 10-year longitudinal study:

Over 10 years, 2/3 of women changed the identity labels they had claimed at the beginning of the study, and 1/3 changed labels 2 or more times. Yet, contrary to the “transitional stage” model, more women adopted bisexual/unlabeled identities than relinquished these identities; few bisexual/unlabeled women ended up identifying as lesbian or heterosexual.

I really shouldn't have to say this, but the thing you identify as isn't necessarily the thing that you are, and especially with cases of sexual orientation there are outside social pressures, many of them religious, some of them not, that are a factor, beyond strictly accurate reporting. How many times have we heard the story of closeted gays or bi folk, afraid of reactions from society? Particularly from heavily religious families that indoctrinate their young people so heavily; it's hardly surprising that people come into themselves and change their label. Sexuality is a gradient, not a dividing line; you can discover things about yourself that you had never known before as time goes on, that hardly means that it's a choice.

Regarding the twin issue, some studies indicate that a genetic propensity is influenced by other environmental factors both pre-natal and early in life; say it isn't purely genetic, but is set by a series of factors beyond your control at a young age. Is that a problem? That's still not a choice you get to make, you know...

Chuckie is out trolling Christians again.

And Heywood's out dodging again, what a surprise.
