suffer fools gladly, does not

Refuses to put up with stupidity. This rather flip rejection of those one considers stupid comes from the King James translation of the Bible, “For ye suffer fools gladly, seeing ye yourselves are wise” (2 Corinthians 11:19). This statement, of course, is a sarcasm; Paul actually is saying that those who put up with fools (in this instance, braggarts) are themselves fools. Today the term is always used in the negative.
