>> because the real goal is not "safety"
Says who ? you ? did you read it on facebook, or did you hear it on an AM radio ? how can you be so sure ?
I for one am European, and a liberal, and i say if you want to own a gun, for whatever reason, and you can prove that you know how to use it and are mentally stable, so be it. I'm not extremely happy about it, but so be it. At the end of the day, i don't care about you owning a gun, but if that gun gets stolen, or goes in the market, and anyone different than you (say a criminal or a madman or a kid) can easily use it, then i object, because i think it's not safe.
Let me rephrase, it's not gun ownership per se that i care about, it's all the he people that get killed using guns, that i care about. I think that's an unnecessary burden that the USA is taking upon itself.
Alternatively, from an economics perspective, you want to have a free market of interchangeable and unsafe killing devices, fine. But then somebody (somebody who buy, sells, or uses guns) must pay for the measurable externalities brought about on the whole society (every life has a value, even just an economic value, leaving aside a lot of more important things, so go ahead and do your math about what the costs are).
And these are costs I do not want to pay, because i don't think it would be fair (for the same reason why i don't want to pay taxes for your truck).
