C'mon---that's a bit of a stretch. We no longer criminalize adultery, and adultery remains socially unacceptable.
Actually, that's about the last one.
But there are many behaviors where morality, self-respect, and character used to limit the action. Just about all of the PC laws came about because people were no longer restricted by those virtues and needed a law to stop the behavior.
Laws against swearing, ethnic jokes, workplace harrassment rules up the ying-yang, public school dress codes, on and on.
My point is, many laws today are in place because people are no longer restrained by morality and character. If a man made a lewd comment to a woman, it resulted in a slap. And that was it. Nowadays, both would race to the courthouse to file a suit against the other.
Now, take a previously illegal activity and make it legal, whoa, Katie bar the door. Homosexual sodomy? Go ahead and say you're against it in public.
Relax the pornography laws and Hollywood pushes the envelope -- where's the outrage?
Gambling laws. We've got local casinos, riverboats, state lotteries -- unacceptable? Puh-leeze. Once it's legal, no one touches it.
