Conservative students are made to feel uncomfortable in college classrooms all the time. Sorry if the Second Amendment makes you nervous.

Many Professors Anxious About Legally Armed Students in Their Classrooms

A professor emeritus at the University of Texas at Austin very publicly quit earlier this month in response to a new state law that allows students to bring their handguns into all classrooms and offices — including his 500-person introductory economics lectures. The professor, Daniel Hamermesh, has become a symbol for frustrated faculty nervous over the spreading of campus concealed-carry laws.

In the wake of recent campus shootings — two in two states on October 9 alone — not every professor thinks more guns are better. Especially since Chris Harper-Mercer, the man who killed nine people at Umpqua Community College on October 1, was reportedly angered over being corrected by Professor Lawrence Levine in an “uncomfortable exchange.” Levine was among those killed by Harper-Mercer a few days later.

A new state law, signed by Texas governor Greg Abbott on June 1, allows students and faculty members with a concealed-handgun license to enter campus buildings with a pistol. Texas law already permits concealed-carry on college campuses, but as of August 1, 2016, concealed weapons will be allowed into almost all classrooms and offices as well.

“With a huge group of students my perception is that the risk that a disgruntled student might bring a gun into the classroom and start shooting at me has been substantially enhanced by the concealed-carry law,” Hamermesh, 72, wrote. He announced his resignation in a letter sent to university president Gregory Fenves on October 4, explaining that he would not be fulfilling his contract to teach fall economics classes through 2017 “out of self-protection.”
