No such thing. Just nonsense. Both the public and the media (even the BBC) thinks the political dialogue, with Mr. Trump as the headliner of course, has never put forth so many lies, untruths, and created such an unreal unworld.
But no, this happens throughout history. In the 1960s most Americans believed that most civil rights leaders, such as Martin Luther King, were communists.
Many societal lies and myths are a result of people’s fears, and play to those fears. What moves society along is the reality and actuality of change. In two decades, for example, few people will think American Moslems are any more likely to be a terrorist than anyone else.
