Why would god create, at all times and in every culture a group of people; whether it's 5% or 10% who mostly have an exclusive attraction to the same sex, not just in a sexual fashion, but in terms of bonding, intimacy, love, commitment and being generally completed as a person by being with that other person...and then condemn it. What a stupid god. And what an even more stupid person you are for accepting that.
this is another form of the theodicy question, which is, in my mind, the central theological* question.
*central to all religions that proclaim the omnibenevolent/omnipotent God, not only Christianity
