I'm not quite sure why everyone is saying that to suggest that being attracted to members of the same sex is caused by your genes is so unacceptable .... I'm pretty sure it is genetic. But the fact that it is genetic is precisely why, as distasteful as I find the idea of kissing a bloke, it is ridiculous to discriminate against or vilify gay people, its akin to objecting to people based on the colour of their eyes or, dare I say it, the colour of their skin. It is probably wrong to say its due to a genetic mutation though. It's not a mutation, its just a perfectly ordinary gene that some people happen to have .
