I have several co-workers who are gun enthusiasts. We talk about guns all the time. We don't really care who overhears us talking about guns or our right to bear arms. I'm waiting for the day when someone in HR tells us we can't talk about guns at work. I refuse to walk on egg shells because I support the US Constitution and the people who died to give me the freedoms stated therein. By the way, my company has no guns signs at every door and even a sign at the parking lot entrance.
