This pattern is a reason why we reflexively hate the crime so. The wickedness is passed from generation to generation.
However, like you suggested, trying to separate it from general unholiness is like trying to identify and take away the worst part of a turd.
“Don’t be spreading turds, no matter on what pretext” never seems to come to some people’s minds here.
The attempt to wall off some sexual immorality from all sexual immorality has been a failure. I wish we would learn.
