You are spot on about the fact that many people judge their own short comings, if they see them at all, as "challenges" but see the short comings of others as "sins". Ideally, it should be the opposite, and if it were, whatever one's theological or philosophical orientation, far fewer people would get hurt in this world.
It is also true that sexual matters are particulalry charged because they are so central to who we are as people. Ironically, that is what the harshest people on both side of this debate agree upon, and why they fight so hard for their respective positions. Perhaps they could each recognize that to the extent that they both appreciate the importance of sexual identity and practice, they could agree to discuss it in ways that didn't always seem to demand one side denigrating the other...
