Gay Conversion Prayer

I was listening to an item on the radio the other day on gay conversion therapy and it stimulated a thought.

Now prayer has been shown to work, if it works at all, only if the person being prayed for is aware of him or her being prayed for, suggesting that one's frame of mind is important in the efficacy, which turns prayer into a form of therapy, rather than a metaphysical intervention.

Imagine, if you will, a group of religious people, one of whom is gay and all of whom believe fervently in the power of prayer, praying that their gay member converts to being straight, but the gay person being prayed for has no desire to convert. Would this be mental abuse, given that all the parties believe in the power of prayer? I would suggest it does. Should the gay person being prayed for not believe in the power of prayer, it would not constitute abuse, just a bit of Tom-foolery.

One person on the discussion countered the idea that praying for a person to covert from gay to straight was useless, as it is like praying for someone's eye colour to change, which is a valid point. 

He also said that if you could covert someone from gay to straight through prayer, it should be possible to convert a straight person to gay by prayer. The flaw in this argument is that an allegefly benevolent god would not facilitate, by intervention, something that is an abomination in that god's eyes - prayer is not independent of the god's will, as it only works through said god, if you believe in metaphysical intervention. However, praying for something that is against the god's will would be deemed witchcraft and require the intervention of Satan, so if you believed in the supposition, you would have to believe in Satan.

Analyse and discuss.
