Well, thank you for your homophobia?
Yes, it doesn't work that way; sexual orientation is something you can't help. If you're a lesbian woman, even if you're born in a country that has the death penalty for homosexuality (all of which are islamic theocracies), you're not magically able to undo an inborn trait. Much like you (as in Barakata) can't be converted into being attracted to women, and only women, lesbian women cannot be converted into heterosexual, or, for that matter, bisexual.
Religion, on the other hand, isn't inborn. It's a fleeting social construct, far more religions have died and left no trace in history than the ones that are extant or historically recorded. If all written and oral records about Muhammud disappeared, islam would never arise again. Like all other religions, it is a fairy tale.
Lesbians have existed for thousands of years before islam rose, and will continue to exist long after it disappears.
It is very vile that you should compare them.
