Depends on where you draw the line, truth be told. I mean, eveyone should have certain rights, but when you start taking away rights without just cause (and I don't mean justification here, as if you are a little on the smart side and take enough time, you can "justify" darn near anything, no matter how convoluted the logic), then you are violating basic morality.
If it's ok for Tom to have a car, but you say Joe can't because you don't like his god or some such, well, that's just wrong. Now, when we talke about biological or nuclear weapons, that's a whole nother story, so to speak.
Now we are talking about things that have absolutely no purpose but to destory, and not even in a healthly, burn the field or forest fire, kind of way, but in the "annihilate" others, and in the case of bio-war and nuclear fallout, in a hideous and painful way.
I think, no, I totally believe, that removing such things from play is the only intelligent move to make. There is the old saying that "an armed society is a polite society". This is total drek. Look at the states here. Any schmuk can go get a gun if they have even half a clue, heck, even a quarter of a clue. However, all these guns sure don't make people here politer. If anything, it's probably why we have one of the highest, and I believe that right now, we have THE highest, homicide rate of all first world countries. That's pretty sad, when you think about it.
So, yes, I am all for taking away the Weapons of Mass Destruction. Heck, personally, I think if there was a way to get all weapons that have no other real use than to kill a person (like hand guns, missle launchers, bio-weapons, nuclear, etc) away from everyone in the world who isn't part of a law enforcement agency (and even here there could be some serious reform) without missing any of them, we should do it. I have no problems with rifles and what not. They can be used for hunting, etc. as well as personal defense. However, it's kind of difficult to conceal a 3030 rifle when walking down a sidewalk. So, at least people are less likely to be toating one around and killing folks with it.
In the end, I think we have an obligation to work for the highest overall good, but with some kind of moral limits. Unfortunately, in a world which sways more and more towards amoral on a regular basis, it seems morality, real morality, is becoming less and less important to more and more people.
Well, I think I've "said" enough on this...
