A tenured Texas State University professor who was terminated earlier this month after allegedly inciting violence during a speech has sued the university, CBS Austin reported. In the lawsuit filed in district court, Thomas Alter, the former associate professor of history, claims that university leadership violated his free speech and due process rights and breached his employment contract. 

At a Sept. 7 conference organized by Socialist Horizon, Alter said in part that “without organization, how can anyone expect to overthrow the most bloodthirsty, profit-driven mad organization in the history of the world—that of the U.S. government.” His speech was recorded and circulated by a right-wing YouTuber who had infiltrated the event. Alter was terminated three days later.

In a statement announcing his termination, Texas State president Kelly Damphousse said Alter’s “actions are incompatible with their responsibilities as a faculty member at Texas State University.” Alter told CBS Austin that he did not associate himself with Texas State during the conference. 

“The reasons Provost Aswrath provided for Dr. Alter’s termination are false and give every appearance of politically-motivated discrimination,” the lawsuit states. “In truth, Dr. Alter was terminated because he espoused views that are politically unpopular in today’s politically-charged climate, in violation of his First Amendment right to free speech.”

Alter told CBS Austin that his dismissal “turned my world upside down and my family’s world upside down.”

“Anyone should be able to express their views no matter how unpopular they are without facing the repercussions that many people are seeing,” he added. (Alter had earned tenure just 10 days before he was removed, The Chronicle of Higher Education reported.)

Texas State did not respond to Inside Higher Ed’s request for comment, but a spokesperson told CBS Austin the university declined to comment on pending litigation.
