Well, we also have vaccines to help us skirt -- or brace for -- the worst of what the world can chuck at us. There are all sorts of ways to avoid focus on one thing and pull attention onto another, as flashy magicians, petty pick-pockets, and pokerfaced charlatans all know.
But there are always ingenious methods to pull us back from permanently swallowing The Really Big Lies, too: truth serum, hypnotic therapy, anti-psychotic medications, cult deprogramming methodologies, and so on. Sometimes, even logic comes bubbling up to the surface in the drowning and airless front lines of public thought and reason, but not often.
Usually, we ask fire to fight fire, and ramp up to meet the lathering blather of the moment. But, really, we are free to choose our own weapons in any exchange of ideas, or in any attempt to highlight the utter nonsense of arguments presented to us as reasoned and reasonable notions.
