Marquette University professor John McAdams has been suspended from his position. His crime? Writing on a post on his personal blog that criticized the actions of another professor, who had instructed her students not to voice their opinions if they were anti-gay marriage or anti-gay adoption.

It’s important to note that McAdams didn’t take a policy position in his post. He simply made the suggestion that – gasp! – students should have the freedom to voice their opinions in an academic setting. Sadly, as McAdams accurately points out in his post, “Of course, only certain groups have the privilege of shutting up debate.”

The university has said it will reinstate McAdams in 2017 if he issues a public apology and acknowledges his “guilt”. Here’s his perfect response:

Cases like this one are the reason why Marquette is quickly becoming known as one of the most intolerant universities in the country. Just last month, the Foundation for Individual Rights in Education (FIRE), a leading organization defending freedom of expression at American institutions of higher education, included Marquette among its list of the “10 Worst Colleges for Free Speech.”

Students and faculty across the country are finding it harder and harder to speak their minds without being penalized by their schools and put through the wringer with vicious social media campaigns. They’re quite literally being ran out of the system.

McAdams told Campus Reform he intends to follow through with his lawsuit against Marquette for their infringement on his academic freedom, which he says was guaranteed to him as part of the school’s policy.

He also issued a chilling warning: “This is reminiscent of the Inquisition, or the Stalinist show trials of the 1930’s.”

If that kind of comparison doesn’t start opening eyes and changing minds, nothing will.
