Two people have accused a tenured professor of bullying gay students.

Christina Santiago, a graduate student at the Indiana University of Pennsylvania (IUP) located in Indiana, Pennsylvania, told CBS affiliate KDKA that the professor told students that being gay is “disgusting, unnatural and abnormal.”

“I raised my hand and I asked the professor, 'So, are you saying that students like myself who identify as homosexual are disgusting, unnatural and abnormal?' And the professor replied, 'Yes,'” Santiago told a reporter.

Michael Heller, an IUP graduate, recalled anti-gay taunts from the same professor five years ago: “God created Adam and Eve, not Adam and Steve, and that being gay was an abomination, and that anybody who was gay was going to burn in hell, and that's what they deserved.”

Santiago, who is no longer enrolled in the professor's classroom, filed a complaint with the school. Last week, students held a demonstration to protest the professor's anti-gay comments. The school says it is investigating. (The video is embedded in the right panel of this page.)

The events come just months after the school's ex-president, Lawrence J. Pettit, suggested in his memoir If You Live by the Sword: Politics in the Making and Unmaking of a University President that gay baiting played a role in his 2001 firing. He's since denied he's gay.
