Too many people are getting hung up on whether they like concealed carry or not. This is a question about federalism. There is a constitutional right to something. Tradition says that a right can be regulated by the states (within constitutional limits of course). So when does one states regulations force another's to recognize it? If you can drive in one state, must you be able to drive in another? If you can marry at 13 in one state, must others recognize your nuptials? We say yes to those. On the other hand, one state may have licensed you to pursue your career as a lawyer (economic freedom is, after all, an intrinsic constitutional right), while we allow other states not to recognize that states license. IMO a concealed carry permit is more like a drivers license than a law license. To those who would argue that a difference is that a concealed-carry permit holder may pose a unique risk to society, I would argue that a partying teenager behind the wheel on spring break offers at least as much danger to the state they are visiting.
