By the way, if you are an evolutionist, how do think homosexuality, if it is a normal condition, evolved as an adaptation that is beneficial to the propagation or survival of an individual's genetic traits? It may be "common" in the natural world, but I still maintain that it is not a condition that is normal.
There appears to be, indeed, some genetic connection and developmental connection to homosexuality (e.g., a male child has an increased likelyhood of being homosexual if he has more older male siblings born to his mother)
So, by the way, if you are a Christian, how is it that God makes individuals born to be homosexual?
