The worst waste of time is arguing with fools and fanatics who do not care about truth or reality but only the victory of their beliefs and illusions. Never waste time on arguments that don't make sense. There are people who, no matter how much evidence we present, are incapable of understanding, and others are blinded by ego, hatred, and resentment. All they want is to be right, even if they are not.
When ignorance screams, intelligence is silent.
