I do tend to agree that the RKBA should not be infringed. If states require licenses to carry a firearm, however, it is well within their rights to not recognize licenses issued by other states. Push toward constitutional carry, not toward forcing states to recognize licenses issued by other states.The right to bear arms is not a state's right. It is an individual right enumerated in the Constitution, one that neither the federal government nor state governments has any authority over. I feel like people who champion states rights don't even understand it.
The federal government has certain powers granted to it in the Constitution. The Constitution also list certain things no government has the power to do. All OTHER things that don't fall in these categories (bearing arms DOES fall in one), are delegated to the states or the people. It is not simply that the states have the right to do whatever they want.
