The place where Diuretic's premise fails resides primarily where he demands that the prohibition of others owning things is validly founded upon his refusal to accept the reasons that those others cite for needing said things--he says they don't need them, therefore they shouldn't have them. Period.
As Bern80 (and you also) pointed out on several occaisions, this assertion is subject to the most virulantly wild flavor of hypocracy.
I don't really give a shit about gun control, but I have been paying some attention to this thread, and it seems to me that there has been an almost intense effort to misunderstand Diuretic's basic argument.
If I have read him right - and I am pretty sure that I have the gist of it - his argument is relatively simple and wholly reasonable.
1. People only need (generally) automatic weapons to satisfy wants (such as range shooting). They do not (generally) need automatic weapons for self-defense. They may need some level of weaponry more lethal than a club (e.g., a handgun), but they really don't need automatic weapons.
[People can disagree with this, or take issue with the "generally" aspect of it, but really, the idea that it is often (or hardly ever) the case that in the US a person's existence rests on their ability to procure or possess an automatic weapon is silly. I am not saying it never happens, but I am saying it almost never happens.]
2. Since autos aren't needed in this sense (e.g., the way that food is
needed - for survival) one should subject them to a cost/benefit analysis to determine whether this "want" (for the possession of automatic weapons) should be permitted.
I am guessing that Diuretic feels that automatic weapons don't pass this threshold. I am inclined to agree, although honestly, since owners are frequently the people shot with their own weapons, I don't give a shit.
His argument if I haven't gotten it wrong (and please forgive me if I have Diuretic) is neither illogical, nor silly. It is based upon a set of values. It is based on an evalution of benefits and detriments. However, so are almost all arguments.
The part that is really repugnant to sense (and entirely undefensible) is this notion of his that his (or his government's, or some government's) whimsical notions of what our needs are should have greater validity than our own notions of what our needs are.
How do you survive in the world? This is happening to you all the time. The government tells you that you don't need cocaine, nuclear devices, fireworks, anthrax, teenage hookers, child pornography, etc. How do you manage to deal with all this control?
