I understand that there are many "interpretations" of Scripture but there is only one true understanding of Scritpure. Part of understanding Scripture is to love the gay community and share the gospel, which does not include bringing up specific sins. It is then up to the individual to make a decision.
When a person comes to me and is confused about their sexuality they come to me because we are both Christians and the person wants to understand what the Bible plainly teaches. I do not dwell on the 7 or 8 verses dealing with homosexuality as a sin. We discuss what their goals are and why those goals are important. If their reason for seeking change is not a good reason (such as seeking societal, religious, or family acceptance) I refer them to "Desires In Conflict" by Joe Dallas. You might like to read the opening chapters where Joe bluntly tells those who are seeking change only for societal, religious, and family acceptance to forget change and simply accept themselves and their feelings and forget even trying to change since they are doomed to miserable failure. I give seekers the same answer Joe does; count the cost and the cost is great before you set your feet on this path. It is neither quick nor easy.
Your analysis of the ex-gay movement is so far off the mark it is ludicrous.
