How to properly understand the story of Sodom & Gomorrah:

I debated this issue on Jim Price's website. Note, I am not arguing that the Bible is neutral on the issue of homosexuality (I'm not trying to argue away Leviticus). Rather I am asking, if this story literally happened as the Bible says it did, what does it tell us about the issue of homosexuality. I argue it tells us nothing about homosexuality as we presently understand the phenomenon. Note: I didn't come forth with this line of reasoning. The late John Boswell is most famously known for it. But I do agree with it, as a matter of logic.
