Where a community HAS standards, there would be no need for such a law. Store owners wouldn’t stock it, children wouldn’t want it, and parents wouldn’t allow its purchase.
America’s very rigid and strict community standards were enforced through community shame - not law.
Law cannot make one moral. If a Saudi Arabian doesn’t drink in Saudi Arabia it is because there is no alcohol available. If the same guy doesn’t drink in America it is because he is obeying his religious restriction on drinking.
As a youth many years ago I worked in a small cigar/lunch/soda fountain store. The store had a magazine rack. We had to make sure that the risque magazines that just showed women in negliges were buried out of plain view. I believe the moral standards have changed. I believe that if the change is natural it still has been pushed along by movies, drug concerts, and a host of other influences the most of which is money, honestly earned or otherwise. Try going back to the days of moral influence and good luck.
LOL, the Supreme Court just disallowed those community standards, you guys have been doing that since the 60s.
