The more a theistic person studies human behavior and the reasons why we do what we do, the less likely a God has anything to do with our way of life. But this false premise still does not cancel the the concept of a God. Only our perception of a God simply changes with the knowledge of the moment. That to me is the challenge of a believer, trying to make sense of book that is looked at as infallible.
Suavojr-
The concept of 'God' and the perception of said 'God' is one and the same.
Discard whatever notion you have been taught 'God' is (angry old man in heaven dispensing punishment and suffering) and the word 'God' will start to take on all new meanings. Interestingly, the Bible makes it clear what God is all along- God IS Love, above all things. And if YOU are made in that image of Love and you don't hate gay or lesbian people, then what makes anybody believe that God DOES hate them?
The reality does not contradict what is written Biblically of 'God' concerning gay people. There is no record of any fiery punishment descending on a gay person anywhere, no matter how hard you look for it.
