Allow me to join in to this Excellent Discussion?
First, and foremost, As a Native Texan and very Proud of it, The RIGHT to possess and carry a firearm is the right of every CITIZEN. Texas has chosen a path of moderation to this touchy subject! A lot of city folk move to the country and don't understand the ways of living in the country. When a person chooses to Open Carry or not, that should be their decision! Personally, I choose not to open carry for the reason of not drawing attention to myself. When I see a A4 (M16) hanging from a shoulder in a Downtown area, I've got to wonder about the person's decision making capability. Not saying they don't have the Right, but Rights have responsibilities that don't always get used wisely!
As a resident of New Mexico (an Open Carry state), It doesn't bother or surprise me when I see an open carried firearm. It is their right to do so!
