All evidence points to natural explanation of sexual orientation and homosexuality exists in almost every animal species.
Religions come from times when people had very limited understanding of the world we live in. World is not as black and white as religions try to paint it. Human biology is very complex, specially gender and sexuality does not exist in black in white but in many different shades of grey.
Just check this such a marvelous evidence he produced, and let me rephrase it..
" All evidence points to natural explanation of (corruption) exist in almost every animal species"
Hence it's proven homosexuality/corruption is natural to human...
This is the caliber of these people, and yet they call religious people blind followers...
Religion makes more sense to human conscience then science does, and considering the fact that science has been wrong about many things in past, science or scientist pay attention to their own credibility before it claims everything to be true what it just perceives
