The Constitution is not written in stone. It evolves as our society evolves. The Second Amendment is more complicated, however, because it deals with issues larger than freedom and oppression; it deals with life and death.
Buried in the Second Amendment is the right to self-defense, the very mechanism that allowed our Founding Fathers to win freedom from tyranny. Some argue it is the right that guarantees all other rights. Our forefathers wanted us to be able to protect ourselves against outside threats, and even from internal tyranny. They may have even intended us to be able to protect ourselves from each other.
It is a stretch to argue they intended guns to be so available, in such strength, that children, high-school populations and co-workers and law enforcement could be so easily slaughtered.
A gun in the hands of a law-abiding citizen is the perfect, unassailable instrument for self-defense and for the protection of one’s family. To tell someone who is acting reasonably and rationally that they have to give up that right is unfathomable to the responsible gun owner. That’s why gun rights advocates have such a negative response to any perceived restrictions on gun ownership: They know, without question, that they will only use their weapon properly.
