In my opinion, there are two types of activist.... There are those that go overboard and always dress in military attire, carry a pistol everywhere, are members of the NRA, shoot regularly, own many military weapons and are generally aching for a situation where they can use their weapons.... then there are people that believe that gun ownership is a necessary tool in the balance of power between the government and the governed (as it was meant for in the constitution) and it is a personal choice whether to own one or two but is not a means as to wish to provoke hostilities or violence and is a great responsibility not to be taken lightly. Generally these people (like me) believe that gun ownership should not be taken as if you are going to war tomorrow but rather just the fact that owning the weapon is not just a right, but a gesture to the government that in order to grow bigger, they would have to subdue the population. The founders did not intend on people carrying weapons around on their hip like they do today with a permit. It was simply a means of survival (hunting, protection from Indians and raiders or animals, and as a governmental balance of power).
The second amendment goes back to when the English armies, before the Revolutionary war, would raid houses for weapons and secure gunpowder reserves in order to forcefully exert the King's wishes on the population of the colonies. The founders always wanted Americans to have the power and ability to rise up, if necessary, to take back the government if needed. But, they also thought it wouldn't be necessary if we had leadership that represented the people effectively and created an environment that facilitated individual "pursuit of happiness".
