Why single out s as "sinners"?

I get your point. I'm just waiting for some Christian group to put a measure on a future California ballot to make adultery a crime. Won't happen, though. Never in a million years. Even though adultery is specifically condemned by God in both sets of Ten Commandments and is the cause of broken marriages, they won't go for it. Too many of them commit adultery and the rest are a bunch of hypocrites.
