Some guy on Twitter said, "Democracy is by definition the antithesis of tyranny."
Well, tyranny has several definitions, but I figure he's using the common one, meaning an out of control government that does not respect citizens' rights or legal restraints.
So I respond, "Well, no: if the people rule without constitutional constraint, that is mob rule, a sort of tyranny."
His response? "Who is ruling without constitutional constraint?"
The question on the table was whether by definition tyranny is the opposite of democracy. But is soon as he realized he had lost on that topic, he immediately change the subject to the question of "Right now, is our current democracy a tyranny?"
Obviously a very different question.
It is impossible to have a rational discussion with someone who does this: it is like trying to shake hands with an eel.
