Just for the record, this is exactly what the majority of denominations believe. I know this because it was a subject that was discussed at a nationwide/multi-denominational Christian conference, called Spring Harvest that we went to last year.
Incidentely, it was lead by a Christian who was gay. He was born that way and for a time was a violent (literally) protester against Christianity. This all changed one day when he stormed a church who followed the Bible and not their own interpretation. He was not kicked out (even though he deserved to be arrested), and ended up giving his life to Jesus when a little old lady (God works in mysterious ways

) gently told him that he was a child of God's who loved him for who he was. He immediately knew that God loved him regardless of any of his sins. Obviously, he was still gay, but as he got closer and closer to God and with the non-judgemental support from the Christians around him, he found his desire for men had faded. He was living within God's heart for him. He is now married (to a woman) with a couple of kids and runs a support group for both Christian and non-Christian homosexuals, and knows/feels he is living as God originally intended him to be. He now teaches exactly what NCdisneyfan said here, because that is fact. He was shown this in practice, however, when the little old lady followed the NT instruction to "Love your neighbour as yourself".
My point is to show the theory of what NCdisneyfan said in practice. I'm not saying that we are all better off being straight, married with kids (however he and thousands of other Christians who were gay do say they are), but that if Churches/denominations followed God and his word, not their own desires, well....to put it bluntly .....it works. This guy followed God and his word, he didn't join a denomination that suited his desires, and his life is now radically changed, and in his words, not mine, for the better.
The majority of churches will show exactly this same non-judgemental behaviour that this chap recieved, not, as I feel a lot believe, that the "non-liberal" denominations will banish them from Christianity. I am sure many will have stories like that, and I am not surprised, but people who behave like that in the name of "religion" are not following Christ.
