Torn,
ISIS is also throwing gay men off buildings. Fornication is a man-made concept. It was invented to control sexual urges at a time when emerging societies did not have the resources to deal with children without baby daddies and the like.
The entire concept of pornea/fornication is fabricated. As long as you hold onto that concept, you will judge gays, people living together, teens experimenting (which is called normal), etc. as deserving of death. Is that really what you want to believe and be known for? Really?
I would suggest losing the term fornication. It is meaningless; it is a loaded word with pejorative death dealing connotations that needs to be thrown onto the ash heap of the 12 Century. Why we still use that word in the 21st Century speaks poorly of us as a species.
