Tolerance used to be understood to mean respectfully disagreeing with others. It implied the fact that two people differed on some matter. But today it has come to mean something quite different. Today it means you must agree with someone or else. Today it basically means, ‘Shut uppa ya face’.
Those who shout the loudest about tolerance and acceptance and inclusion are usually the most intolerant, non-accepting and exclusive folks around. So we have gotten to the place where it is time to start getting intolerant about tolerance.
I have already offered some incisive quotes on tolerance by Fulton J. Sheen, so I will not offer much by him here.
