The punishment fits the crime

What the story of the Tower of Babel tells us is that there was originally only one pagan, anti-God religion in the world.  At the Tower of Babel, God acted to diversify paganism.  All the heathen religions in the world have the same basic ideas, but each is slightly different from the rest.  One group worships Thor and his kin, another Zeus and his family, another Jupiter and his cohorts.  One nation favours Baal, another Chemosh, another Molech, and another Amon-Ra. One group of revolutionary socialists follows Marx-and-Lenin, another follows Marx-and-Mao, another Marx-and-Castro, and another Marx-and-Ho Chi Minh. Still others follow Adolf Hitler.  From the Christian point of view there are not many differences between these pagan religions.  Each pagan nation has its own "gods", and wars are fought over them.
