I call it "conditioning." Seventy years ago, my parents and my teachers would say "shame on you" and I would turn red-faced. Why?
Sin has, and always will be, with us. We are all sinners, but 70 years ago it was a crime to do immoral things. Then Neo-paganism (neither Christian nor pagan) acceptance and tolerances set in. Conditioning.
One very small example: People used to sneak to a bootlegger, then we evolved to legalize package stores to brown bag our purchases. These stores had to maintain certain distances from churches and schools. Now, go to grocery stores and load up your buggies. It's now legal. No guilt or shame?
From the White House to the church pulpits, the Ten Commandments are systematically and deliberately disobeyed. After all, "God Himself" is a common byword, hell is a scare tactic, the sanctity of marriage is not respected, so it has become legalized adultery. Unspeakable abominations are now alright as long as people have affection for each other — flaunt it down the public streets. Truth is now managed and edited news.
"Were they ashamed when they had committed abominations? nay, they were not at all ashamed neither could they blush: therefore they shall fall among them that fall: at the time that I visit them they shall be cast down saith the Lord" (Jeremiah 6:15, King James Version).
