After dealing with an extremely difficult class, Texas A&M Galveston Professor Irwin Horwitz decided to fail all of the nearly three dozen students who took his course.

According to Horwitz, an instructional associate professor in the university's department of maritime administration, the students were disgraceful and lacked maturity. As a result, he sent them all an email explaining that they would receive a failing grade in his Strategic Management class, and that he would no longer be teaching the course.

"Since teaching this course, I have caught and seen cheating, been told to 'chill out,' 'get out of my space,' 'go back and teach,' [been] called a 'f--king moron' to my face, [had] one student cheat by signing in for another, one student not showing up but claiming they did, listened to many hurtful and untrue rumors about myself and others, been caught between fights between students," Horwitz wrote in the fiery email, which was published by Inside Higher Ed.

"None of you ... deserve to pass, or graduate to become an Aggie," he said.

In an interview, Horwitz told CNN affiliate KPRC that he reached a "breaking point" after dealing with disrespect.

Horwitz had enough of the behavior. It was so out of control, he said, that there were security guards in two classes.

"It became apparent that they couldn't do some of the most simple and basic things they should have been able to do," said Horwitz. "This class is unique. I have never failed a class, it is very rare that I fail students, sometimes learning incorporates tough love."

On the other hand, senior John Shaw said that the failing grade was unfair.

"I had never had a problem in the class. I thought I had done pretty well, done pretty well on the first test and then I get an email saying I am going to get an F in the class, it was overwhelming," Shaw said.

Fortunately for the students, Texas A&M Vice President of Academic Affairs Patrick Louchouarn told KPRC that the failing grades will not stick. The "only reason a student would fail because he or she has not performed the expectations for that particular class," he said.
