@joelle Most if not all of that disapproval is based on interpretation of the bible. The bible was compiled 300 years after the fact. It was heavily edited with scriptures not representing the ideas of the pope of the day just being burned. The bible is basically one man's decree as to how people should live.
I notice that in non Christian cultures, transgender seems more accepted. The faffafini in Asia, theres a group in India. Not sure if they're called hiru.
It leads me more to think that the bible is too restrictive. Mind, eastern religions are more about how to live while western religions are more about how to prepare for death.
