“Never argue with an idiot. They will drag you down to their level and beat you with experience.” ― Mark Twain
As it is rightly said, arguing with an Idiot is a waste of time. You know that a particular person, a family member, colleague or boss is an idiot, the only thing you can do is to ignore him/her. Try to be silent around them and do not indulge in unnecessary conversation with them.
We call people with low IQ as idiots. Most of the time idiots won’t agree that they are idiots. This may due to ignorance, denial and most of the times stubbornness.
