The religious argument is a flawed one. Due to the practice of secularism amongst nations, the idea that federal law should cater to religious doctrine is somewhat of a bigoted view point. The way an evangelical christian views the world should not be indoctrinated to non-evangelical Christians lifestyles by force. The way a Hindu views the world should not be indoctrinated to non-Hindu's lifestyles. The way a Jewish person views the world should not be indoctrinated to non-Jewish people's lifestyles. So on and so forth..
