Yes, science had found a gene connected to homosexuality but it doesn't mean it's mutation or something like that. Illness is defined like that: it must be harm your body physically and psychologically. Some scientist can say it's illness with their articles, I've read them too but they always end up being wrong. Even WHO says it's not illness, plus what we learn from genetic school it's not illness, even a little. So there is nothing to be cured. But there is really something that has to be cured: homophobia. To hate people, just because they are different from them, is a illness, a big one. We have to understand one point. Homosexuality isn't a choice, it's a inclination like heterosexuality. You all can see the proof from the nature. If people are not considered as a proof on that matter because of using their brain, you can still see some of other animals are homosexuals, not choosing it, it's their instinct.
