I have heard the same thing. I have also heard that the one NT scripture used to justify prohibitions against same-sex relationships was talking about something entirely different than loving, committed couples, based on the language used in the original writings. The best I can say, though, is that it never made sense to me why a supposedly just, loving God would tell people who are same-sex loving to either remain celibate or suppress their natural inclinations and enter into opposite-sex relationships. That seems neither just, nor loving. I struggled with the idea until I came to the conclusion that a just, loving God would not be so callous.
