"Privilege?"
Your use of that word in the context of owning and keeping a firearm is part of the problem right there. Since 1968, our nation has endured some 40 years of increasing rhetoric designed to convince us that owning a gun was merely a privilege bestowed upon you by the Powers That Be instead of a Constitutional right. But you and I are also intelligent enough to know the dangers of leaving unsecured guns around where kids or the mentally ill can get them, and we adjust our behavior accordingly, not our rights.
A well-regulated militia is also a well-educated militia. That's why I always stress education, education, for the love of all that's holy, education. At home, at school, in the community, education should never stop. That way, when your son goes to purchase his first gun ever, you know he won't screw up instead of crossing your fingers and hoping for the best.
Education is what separates militia like you and I from jackals like the Taliban, Janjaweed, and The Order.
