Here's the rub in the secular world. While it is a sin and it happens to the best of us, the evangelical + wing of the conservative movement comes at the secular world every day with the problem is God has been taken out of the schools. If God were allowed back in the schools, then much of our sinly nature would be curbed. Secondly, the same folks claim that "Godly and a family unit of values" is a natural remedy for these types of "worldly problems". There was also a thread on this forum that discussed the probable link between homosexualality in children and some sort of traumatic abuse of physical, sexual or verbal varieties.
Clearly, as we can see with Keyes and many other promeninet conservative individuals the remedies cited above are not the elixir that cures all. And are you open that the cause of Maya's current problem may be that she was somehow a victim of abuse?
That's not to say that a little more faith wouldn't help, but it's not the cure all it's portrayed to be.
It's possible. Lot's of things are possible. But judging from what we know, the Keyes are taking the right approach.
