The long-smoldering struggle between Marquette University and a prickly professor made the Washington Post this week. But there's something funny about the headline:

A university moved to fire a professor after he defended a student’s right to debate gay marriage. Now he’s suing.

A little surprising, in itself, I guess. But what if I told you it's a Catholic university? A Jesuit one, at that? If criticizing gay marriage -- quoting, for example, the teachings of the Catholic church -- during a discussion in class is not allowed in a Catholic, Jesuit university …?

There is a good summary at the top of Post story, at least:

The conflict began in 2014: After a student complained after a philosophy class that he was disappointed that he and others who question gay marriage had not been allowed to express their views during the classroom discussion, the graduate-student instructor told him that opposition to gay marriage was homophobic and offensive and would not be tolerated in her theory of ethics class. John McAdams, an associate professor of political science at Marquette, blogged about it, writing that the instructor "was just using a tactic typical among liberals now. Opinions with which they disagree are not merely wrong, and are not to be argued against on their merits, but are deemed ‘offensive’ and need to be shut up."

The story went viral, touching as it did on the heated debates over issues such as campus culture, gay rights, academic freedom, whether students should be protected from comments they find offensive or hurtful, and where the lines should be drawn in discussions of charged topics such as race and sexuality to ensure that people don’t feel stigmatized or unsafe. The instructor was targeted on social media by people angered by McAdams’s account of the incident and ultimately left the university.

McAdams was suspended without pay the following month and banned from campus, and in March of this year he was told by university president Michael Lovell he could not return to teaching unless he wrote a letter acknowledging that his behavior had been reckless and incompatible with Marquette values and that he feels deep regret for the harm he did to the instructor.

On Monday, McAdams and the Wisconsin Institute for Law & Liberty filed a lawsuit in Milwaukee County Circuit Court, claiming breach of contract.

Now, Marquette would never be mistaken for Catholic University of America, in which faculty members are, to some degree, required to stick with traditional church teachings.
