(Apologies in advance for the length of this post)
@Draugnar: First of all, welcome back. I am sorry I was a bit rude about you before when you were mouthing off about leaving the site. Maybe I should learn to control my mouth a bit too. (Well, my fingers, technically).
Second of all, thanks for making such a reasoned argument. I would like to respond (politely, and in the spirit of an informed debate) to what you've said, so here goes:
"I won't say 1 is true, because widespread ownership isn't a net gain."
I am glad we agree on this point. It is a shame Acosmist refused to explain himself on this one as I would have been interested in his argument.
"BUT, ownership of certain weapons CAN BE a net gain to individuals who use them for a) protection of property and b) hunting."
I think the "protection of property" argument is flawed. There are many cases of gun owners ending up being shot with their own gun, by an intruder. Having guns in your home does not make your home a safe place. Furthermore, just because someone breaks into your home (which is of course a crime) this does not give you the right to kill them.
I have some sympathy with the idea of guns being used for legitimate sporting purposes - I would argue that for public safety, such sporting use should be restricted to specific, designated, fenced-off areas, which people can only enter with permission - in order to limit the possibility of other people straying into the area and being accidentally shot. I also think that in between each use, the gun should be kept locked up at a designated gun club or similar, licensed, sporting club premises. People should not be allowed to keep sporting guns in their homes. Unless you plan on shooting deer in your bedroom?
"On issue 2. the difference is in the capabilities of said weapon. A flamethrower is a purely offensive weapon and NOT something that could be used by the sportsman/hunter. I also have no problem with a ban on assault rifles or any fully automatic weapon. A semi-automatic weapon carriable in ones hands is the most I think the general populace should be allowed to own. In short: one shot, one kill. Flamethrowers can kill entire rooms of people, as can large bore weapons like a tank cannon."
A handgun can kill entire rooms of people. It kills them one shot at a time, but it can kil them.
"But your argument can be twisted the other way as well. If you are going to ban all guns then what's next? Knives designed for hunting or paramilitary knives like my Marine Corps K-BAR? The K-BAR is a killing weapon originally designed to not only be utilitarian in ature, but as a means of defending oneself should he be caught away from his firearm."
I certainly think there is no reason for a normal person to own a huge military knife designed for combat. I would support restrictions on these knives, as they are primarily intended as weapons. Why do you own one?
"Yes, banning people from bearing arms IS an intolerable right as the Constitution of the United States declares it so and the United States Supreme Court for the last 233 years has upheld that constitutional right."
I was arguing from the perspective of a UK citizen, where your constitution does not apply. I understand that the US constitution is something many US citizens feel very emotional about, but a lot has changed in the last 233 years, hasn't it? (By the way it's actually 217 years, not 233 - your Constitution's Second Amendment, the one about bearing arms, was not adpoted until December 1791)
"We have this right to guarantee that a repressive regime will not be able to take over our country for our people will be armed to rise up against said regime."
This has been the subject of intense debate, but many scholars believe it is clear from the wording of the Second Amendment that it was NOT intended to arm the citizens so that they could rise up against the government - but simply to provide an armed militia that the goverment could call upon if the United States were invaded, or in other times of need. Such a militia is no longer needed.
"As far as banning them goes because of the violent crimes and murders they are involved in... You do realize that, in most cases, the guns used in the commission of those crimes are black market, unregistered weapons? Banning gun ownership amongst private citizens will just make the black market that much more lucrative and will do nothing to stop gun violence."
Many guns now circulating illegally originated from a legal source. In your part of the USA, Draugnar, does the government regularly visit your home to check that all the guns you have ever legally bought are still in your possession? If they do not, what's to stop you buying a gun, legally, in a licensed gun shop, and then selling it on, illegally, to someone else?
Secondly, banning gun ownership amongst private citizens sends a powerful message that guns are DANGEROUS and that regular people should NOT have them.
It is certainly the case that if the US banned gun ownership, there would be a considerable and difficult transition period, due in no small part to the way gun ownership has become so accepted and commonplace in your society. Massive law enforcement resources would be needed to ensure that black market weapons were seized and destroyed. I do not claim this would be an easy task.
"And yes, I know the escallation argument. If everyone had a semi-automatic pistol, the criminals would just get automatic assault rifles. News flash, they already have access to them if they have the cash, but you typical home intruder doesn't have the cash to get a black market AK47 or UZI."
But this exposes another problem: Lots of US citizens own guns. Yet lots of burglaries take place. Why is this? If letting people have guns provides a genuine deterrent to house-breakers, why is this not reflected in your nation's crime statistics for burglaries and robberies?
"So banning semi-automatic handheld weapons is both a violation of my right to bear arms..."
But isn't banning automatic weapons, which you are in favour of, ALSO a violation of this right? Isn't banning flamethrowers and rocket launchers a violation of your rights?
"...and it would expose us to a potentially corrupt government running roughshod over our rights (the Supreme Court does that enough today)."
Why don't you rise up against the Supreme Court and shoot them all, then, since you believe this is your constitutional right?
Also, if one of the main justifications for letting you bear arms is that you could use them to overthrow a corrupt or repressive government, isn't this an argument in favour of you being allowed tanks and heavy artillery? After all, the government has tanks, right? So surely if you are going to exercise your constitutional rights and overthrow the government, you'll need tanks as well!
