BBE, I agree with you to an extent. I don't care what people are. I think it's a shame when people feel forced into a choice that isn't their true desire, be it a het woman living as a lesbian due to her feminist position, or a gay man marrying because it's "the done thing".
But I've always opposed Christian bigots on 2 fronts, firstly that there's no problem in being gay anyway, and secondly because it isn't changeable or curable.
But you have to remember that the gay people in question are Christian, which is why they fall under the influence of these bigots. If it's true that they can be "cured" of their homosexuality, and due to their religion, they want to be cured, then it's fair enough.
Personally, I don't think sexuality is fluid or changeable. You are what you are. You were born that way. I think believing you can change and going thru treatment to change is not going to end happily, and is not good for your mental health.
