The lessons of history are often ignored by generations to follow. The realities of war, political process, and social norms often repeat themselves as you very well know.
There was a dark time in our history when liquor was banned due to mad people believing that a reasonable adult could not make an educated decision to consume a product that's existed for hundreds if not thousands of years. Overwhelming zealotry went masquerading as parenting and as a result the so called moral brigade raised their spears high attacking what they felt was necessary to bring more laws to protect Americans from themselves.
As a result prohibition came into place and the United States became a good idealized utopia. Crime ended, families stopped being dysfunctional, and children had whiter teeth. People suddenly listened to their elected leaders and decided any notion of consuming alcohol was a bad idea.
Of course the opposite is true. After a huge wave of mob violence swept urban America for years taxpayers were fed up with such high and mighty nonsense. On this day back in 1933 an Amendment to the Constitution was passed repealing Prohibition and there was much rejoice. Remember the lessons my friends as many of our civil liberties are under fire in the name of safety.
