As a society, we spend a lot of time laughing at the old fuddy-duddies for thinking that Elvis was going to turn their children into promiscuous tramps, or that no-fault divorce would bring on the break-up of the family, or that having some gay people on TV would lead to immorality and general moral decay. Or that fake art (eg, Jackson Pollack) would devalue appreciation for genuine art.
It's a good thing none of those actually happened.
