We need not justify the exercise of our rights to would-be tyrants

The best explanation for owning guns. Read the whole thing. 

Frank Sharpe explains,

When asked what I do for a living I reply: I teach people how to shoot people. I teach people how to shoot people because some people need to be shot – and they need to be shot NOW. 

Twenty-six years ago I began my involvement with “gun rights”.  I had a good grasp on what Article II of the Bill of Rights was about then, and my thoughts haven’t changed since. Article II is about the individual’s ability to shoot tyrants – plain and simple.
It has nothing to do with hunting, collecting or competition. And tyranny, as I define it, may appear in the form of a rapist in the alley, a mob during civil unrest, an invading military, or one’s own government.
I personally own no “sporting arms.” I own and train with auto-loading, magazine fed weapons; rifles and pistols which are designed to get hot and function during conflict. Most are black and “scary looking”, and that suits me just fine – I’m not in the rainbows and unicorns business, I’m in the force business.

The liberals keep talking about hunting and "sporting" purposes. They need to read the federalist and anti-federalist papers. The founders knew exactly what they were doing.
