What should instructors at a public universities in Texas do when students can carry in class? [View All]

[readmoreoften]

The legislature is about to pass a ruling that students with conceal carry licenses can carry weapons on campus and in class. Many campuses in Texas (particularly the one where I am an interested party) have large class sections (400 student stadium classes with lockable doors), a high ratio of returning vets with PTSD, and a student body raised with very conservative political sensibilities (majority anti-choice, suspicious of global warming, anti-evolution, anti-union). The progressive forces on the campus where I am an interested party are an almost entirely non-activist immigrant/latino population and an outspoken but apolitical LGBT population, which generally has widespread campus support even among conservatives because LGBT issues discussed are campus related (anti-hate crimes on campus, "promoting tolerance", etc.)

In light of the new legislation, what should a professor to do, especially if he/she teaches controversial and required subject matter such as ethics, critical thinking, and biology? Or if he/she is feminist or LGBT?

Posting in GD and not "guns" because I'd really like a wide range of opinions on the matter. This is not flamebait. I'm really looking for suggestions and solutions to a tough situation. I've added choices to the poll that I don't agree with, but ones I have heard from faculty.
