"Okay, then should we register knives, hammers, bows, bicycles, and whatever else could conceivably be used to harm someone else and/or help a perpetrator get away with it?"
How many people are killed every year on the roads? How many are killed by gunfire? How many, exactly, are killed by hammers or bicycles?
"One would probably feel safer in a situation where an angry drunkard might decided to pick a fight when there's easy access to firearms."
So your idea of how to deal with a difficult situation is to have ready the means with which to massively escalate the problem.
"And yeah, the possibility exists that said drunkard might also be armed, but if enough people are armed, that may dissuade him from starting a fight in the first place."
On the other hand, it could lead to a large number of people dying. Just think of the shoot-ups in saloons that are the staple of the old westerns on TV. They don't shoot those scenes because they think it'll look controlled and boring.
I see that you make an analogy to vaccination and cattle. Another group that are vaccinated is children. As you are against any control of adults, whatever their state of inebriation, in having access to weapons, you must surely accept that one would feel safer in a situation where one's child had access to firearms. Not to allow my children to pack heat when going to grade school is an infringement on my rights as a parent and an insult to my care for them as a parent. If they are attacked by an armed assailant, say a teacher or administrator going postal, won't other similarly armed children come to their aid?
Reynardine, I am for a few days back in The Land Of The Free. When it comes to firearms, Kosovo is indeed relatively civilized.
