You're contradicting yourself with nonsense about how firearms are better than a sword at self defense. That doesn't matter.
Guns, swords, bows, spears, pikes, war hammers, cannons, mortars, tanks. All of them are the same, tools designed to do one thing, kill something.
Their ability to kill is what gave them their power, again that power could be used for either destruction or preservation.
That is the simple point that is being made.
No. They are not designed to kill. They can be used for that, but they are designed for defense. A tool the common man can employee with very little training to use correctly and is easy to acquire becomes a tool for good usage. A tool that is only designed for the hands of those that would use them to seek their own greed is not a tool for good but evil.
Swords, and I own MANY, for a long time were not a tool for the common man. They were strictly designed to be handled by men of warfare and used by men of warfare. They were designed to wage war and was only used for that purpose and oppression. Name one country before the advent of the firearm that was as free from oppression as America has been? Or any country since the advent of the firearm?
Do you not see the direct difference? Swords = a tool designed to kill others. It can be used for other purposes. Like I have them for martial training and display because I like the way they look. But their original design from conception was never for protection or defense. A sword being in the hands of a person does not dissuade violence from being brought to bear against that person unlike a firearm. There is no contradiction here at all.
Let me put it to you this way....
A person well trained in the use of a sword see's a common man or peasant at the time with a sword in hand. Do you think the well trained person is at all remotely scared of that sword in the hands of someone incapable of really using it? No. That has always been the case. If the well trained person was seeking to harm that common man with the sword they would have no fear in doing so.
Change that to a common man with a gun. A person seeking to inflict their will upon that man with a gun is going seriously think twice about it. They are more than likely going to outright dissuaded from making the attempt. Because even if they suspect that the common man may not have that much training in the use of that firearm, the risk it has for successful employment in a defensive situation compared to an untrained sword user is far greater.
It can arguably be said that the advent of the firearm and it's usage by the common man as a tool for good has led to the rising of much politer societies. While the world has some throw back to the dark ages countries out there, they aren't the same level of conquering threat they would have been before the invention of the gun. The quote, "An armed society is a polite society" hits the nail on the head in that regard.
