Warning: Graphic profanity.

Video captured a heated confrontation between a Yale professor who criticized a campus-wide email about potentially offensive Halloween costumes and an incensed group of students who swore at him and called him "disgusting."

The students were demanding an apology for an email sent by the professor's wife Erika Christakis, who's a lecturer in early child education.

Her letter questioned whether the email about Halloween costumes had been necessary, and expressed worry that universities had become "places of censure and prohibition."

Her husband, Silliman College Master Nicholas Christakis, defended his wife's comments to the gathering of about 100 students, when crowd members grilled him for an apology.

"I apologize for causing pain," Christakis told the crowd, "but I am not sorry for the statement. I stand behind free speech. I defend the right for people to speak their minds.”

A student then attacked Christakis personally, calling him "disgusting" and a "poor steward of this community."

“As your position as Master, it is your job to create a place of comfort and home for the students that live in Silliman," the student said. "You have not done that. By sending out that email, that goes against your position as Master. Do you understand that?”

Many students are demanding both Christakis and his wife resign.

Judge Napolitano said on "Outnumbered" that he agrees "entirely" with the professor.

"Free speech should reign on campus. There is no right not to be offended. I'll say that again: There is no right not to be offended. Even though this is private property -- the First Amendment does not regulate private party, it only regulates the government -- the people that run Yale have decided that freedom of speech shall reign, and it should. If you don't like the costume, wear a contrary costume. Clothing and costumes are expression. The remedy for tasteless expression is more expression, it's not suppressing ideas."
