If that's the case, does that mean there is no need for laws, law enforcement, or even government? If I'm responsible for my own security, why would I even call the cops? Just handle everything I perceive as a threat to my own security myself.
Individual responsibility for your own actions is all well and good; it's a commendable character trait, but it has to stop short of taking the law into one's hands. My buying a gun is taking responsibility for my own safety and security? And it guarantees my freedom? No, sorry, I disagree with that.
I'm pretty confident the British don't view themselves as "slaves to a crown". They actually began taking action back in the 1500s to limit the power of the monarchy, and they've pretty much been at it since then. If you know anything about the English system of government, you should know that the monarch really doesn't "rule". The current monarch is really just a ceremonial leader...she's the titular Head of State, but really is not allowed any true political power.
I'd go so far as to suggest that if someone were discussing the British political system with someone from England, and mentioned that they were considered to be some sort of "slave", that person might find himself flat on his back, staring glassy-eyed at the pretty white clouds floating by overhead.
I suppose so, but I doubt the young man bought the gun out of any noble desire to validate his freedom. He wanted a gun, hadn't been able to buy one before, so he bought it. I'm not reassured by everyone who buys a gun, though, no matter what reason they give for buying it. I cherish and place a high value on my own personal freedom, but I view maybe 90% of those freedoms as having nothing to do with my ability to walk into my favorite LGS tomorrow and buy any firearm I wish (which I just may do, by the way).
And please don't tell me that thing about all freedoms and all parts of the Constitution hinge on the Second Amendment. They don't.
All this is just my opinion, you understand. It isn't offered up as facts (except the part about the British monarchy). And this opinion is worth exactly what you paid for it.
