A professor at Texas A&M threatened to fail the entire class of strategic management students. Irwin Horwitz, an instructional associate professor in the university's department of maritime administration, said, "I have seen cheating, been told by students to 'chill out,' 'get out of my space,' 'go back and teach' refuse to leave the room after being told to do so following inappropriate conduct, called a 'f****** moron' several times by a student to my face ..."

Finally, Horwitz said, "Enough was enough. It became apparent that they couldn't do just some of the most simple and basic things that they should've been able to do at that point." So he failed the entire class, stating, "It became apparent that they couldn't do just some of the most simple and basic things that they should've been able to do at that point."

Possible Preaching Angle:

Sometimes it's wise not to demand judgment—you (or the entire human race) may not like the result.
