As of about a year ago, I believed in gun control, but after looking at the issue closely, I can't seem to find a good argument for limiting gun rights. To be a free nation, we must begin completely free, and then progressively limit rights only for good reason. Since gun control is a way of limiting rights, the burden of proof lies upon gun-control advocates. That is, those who are arguing for gun control must provide good reasons for limiting those rights, not the other way around. Gun owners don't have to justify themselves, it's those who wish to limit the rights of gun owners that must prove gun ownership to be an excessive right.
In light of this, all that must be done to defend gun ownership is to rebut the arguments in favor of gun control. So far, what I've read are the following:
1) Guns cause crime. Things that cause crime should be outlawed.
2) Guns are dangerous and unnecessary. Unnecessary dangerous things should be outlawed.
I think both of these arguments are very similar and can be effectively rebutted with counter-examples.
1) I not sure how guns can cause crime. It's not like guns whisper into the ears of their owners trying to persuade them to rob the local bank. Maybe it would be more accurate to say "guns are often used in crime." If this is the case, and it's also true that "objects that are used in crimes should be outlawed," then the inescapable conclusion is that cars and ski masks and knives should also be outlawed, because these are also often used in crime. That is clearly absurd, and therefore the premise that "objects that are used in crimes should be outlawed" is false. One possible response is that since cars and ski masks and knives have other uses, they should be legal, but guns shouldn't. But to say that guns don't have other uses is simply false . Hunting, marksmanship, and defense are all valid alternative uses for guns.
2) Similar counter-examples can be used for this argument. Perhaps large chef's knives are unnecessary because smaller paring knives can be used instead, albeit with some extra effort. They are also dangerous. Should we therefore conclude that chefs knives should be outlawed? No, of course not. Therefore, the premise that "unnecessary dangerous things should be outlawed" is false.
From this, it's pretty clear that completely outlawing guns is an untenable position, but the more complex issue is that they should at least be controlled. I have trouble with this, though, because then we arrive at the same absurd conclusions as above. If we need a license for guns, should we also need a license for ski masks and chef's knives? Personally, I'm undecided on this issue.
