Hey, but it might be true!
Prayer might indeed work, only if you pray hard enough.
I agree that the consequences of accepting such a criteria of truth are bad -> a cult leader might say that if we think he is wrong, it is because we do not have enough faith, and then exploit all of us.
But, arguing that the consequences of accepting a certain criteria for truth are bad ones is not the same as proving that it is a bad criteria for truth.
It might be indeed that prayer works only if you have pure faith.
I note that you have avoided addressing the posts that requested you support your claims regarding homosexuality being a choice and that religious treatments work.
