I have had this argument here on NR almost one year ago. There is some scientific evidence of homosexuality in animals, and it is possible that people could be born gay, in a defective way. Since the basis of existence is reproduction, a "gay" species, in the biological sense of the word, would die off since it would be unable to sustain itself. So from this standpoint, homosexuality is a biological defect. But biological no less... Meaning, in some cases, it would exist devoid of choice.
I was throughly attacked here on NR for this point of view. That God does not make mistakes, God does not make sin, God would never allow it to happen, etc, etc, etc...
Take a look at that thread
here
Just nice to see that a religious person can also see things from a scientific point of view...
