"Said Miller: 'If you say that because you are born with a certain inclination then it is God-given and you should be free to follow that through in your life, it doesn't make any logical sense whatever. You would then have to say that there are many different inclinations with which people are born — even if it is true that this is an inherent thing — and which people spend their lifetime trying to subdue. The fact that you are born with it doesn't make any moral judgement on the inclination.... [Proving that homosexuality is natural] makes no difference at all.'"

These rigid, narrow minded haters will have their way no matter what the evidence shows! There is no amount of evidence that will convince them to change their minds, and that is why to try to appease them in any way, to in any way seek accommodation with them, or to try to use "sweet reason" to appeal to them, or to try to get evidence about the inherent nature of homosexuality, falsely thinking that by so doing Gay people will be more likely to be embraced by people such as this, is done in vain.
Smug, self-righteous, and sanctimonious people who appeal to their own flawed and warped understanding of certain selected verses of Scripture, and of Christianity itself, have absolutely NO understanding of the Gospel of prevenient grace (John 6:37; Romans 8:29; Ephesians 1:4), and they have the temerity to elevate their own feeble understandings and biblical interpretations, and their appeal to "tradition," over and above the love of God for all His children, and they have the temerity to teach others to think likewise.
These wolves in sheep's clothing, with their sanctimonious rhetoric and smug beliefs that they have regarded, and would have others regard, as "the Truth," are not only a danger to LGBT people and to other Christians, but by elevating their own discriminatory prejudices, and their false gospel of legalism and exclusion, over and above any possible forthcoming empirical evidence and, more importantly, the love of God, spit in the very face of God Himself!
They miss the message of Jesus and the living of the Christian life, and would have others do the same!
Jesus speaks directly to such people: "Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with their lips, but their heart is far from me." (Mark 7:6)
