IMO the right to carry firearms is an extension of property rights. I have a right to defend my property at home and when I'm traveling in public. However, that right can only exist if we respect the same rights of others. As much as I dislike it, I do support the right of private businesses to determine the carry status in their business. Just as we have a right to not patronize their establishment, they should be able to set the rules of entry. Some here say that the constitution trumps private property rights, but it actually has nothing to do with individuals or businesses. The constitution is quite simply an instrument to control the power and scope of the federal government. But all that aside, lets look at a less hotly debated amendment than the 2nd. Everyone from all parties agrees with the first amendment right? Does that mean that a theater patron can enter a theater wearing a shirt covered in vulgarities with the theater owner having no recourse? Can the same patron stand up in the middle of a movie screening and sing the star spangled banner? Of course not. Private property differs from "public" property in two fundamental areas: #1. You have a choice. #2. You aren't forced to pay for it.
