If you work at a Texas college and are worried by the prospect of having guns in your classroom, relax. The new campus-carry law changes your risk of gun violence very little. I can almost guarantee that if you have a few semesters of teaching under your belt, at some point there have been students with guns in your classroom. If those illegally armed students were not moved to violence by the content of your course or the statements of their fellow students, it seems highly improbable that a new group of legally armed students will prove to be more volatile or violence-prone than their scofflaw peers.
