Call me nitpicky but the statement in bold is wholly incorrect.
The only thing granted by the Constitution are the specifically enumerated powers given to the three branches of government it also creates.
Rights exist (explicitly in the Declaration and, more importantly, implicitly in the existence of the 10th Amendment) without regard to their mention in [strike]the Constitution or the Bill of Rights[/strike] any document whatsover because they are an inherent part of our existence.
The right to drive a car does exist without the Constitution, and no grant is necessary. The state gets away with licensing it and making it a de facto privilege due to the fact you do it on "public" roads.
A 10-year-old is perfectly within his rights and legal driving dad's pickup around the back 40 all day long, and it probably happens quite a bit.
The sad part is, by allowing the state to license carry, it has become a privilege just like driving.

Just call me nitpicky.
