However that's entirely different from what the anthropological and biological community thinks about the origins of homosexuality. It may not be a "disorder" but no one is sure whether it's biologically "normal."

It is only exhaustive for people outside of academia trying to paint a picture of the biological world according to a social ideal rather then a scientific truth.
