The worst waste of time is arguing with a fool and fanatic who does not care about truth or reality, but only the victory of his beliefs and illusions. Never waste time on arguments that don't make sense. There are people who no matter how much evidence we present to them are not in the capacity to understand, and others are blinded by ego, hatred and resentment, and all they want is to be right even if they are not. When ignorance screams, intelligence is silent. Your peace and quiet is worth more.
