Hate to tell ya.......but I've attended Catholic, Lutheran, Episcopalian and both Northern and Southern Baptist churches (orphaned at 8 and in foster care until 16), and ALL of them taught that story was about gays and living in sin.
I've also been Lutheran and Catholic and I've never heard it explained that way. As a matter of fact I've never heard any preaching or any sermon on being gay at all. This story is about the evil of lust, lust comes in many forms, and lust without love, the search for only physical pleasure without engagement of the heart, is considered a sin.
The Lutheran church I now go to is an accepting and open church. We treat gays and lesbians the way God wants us to.
If you have never heard any preaching or sermon in a church on being gay then you have never been south or west of New Jersey or east of Nevada.
I could show you 107 within 20 miles of where I live.
But I am pleased to state that even the southern Baptists now acknowledge it as same sex attraction and that folks are born with it. Most of them have dropped the idiotic catch phrase "they learn it,it is a choice and they are not born with it" BS. They admit they are born with it but state the Bible says not to act on it. Not all of them but a lot and I know many that adamantly oppose it in their religous life but do not judge in their life in society.
That is probably you. I disagree but we each have our own religous beliefs. As long as folks get equal civil rights I could care less.
