The image that comes to mind is guys who might in one instance have solved their disagreement with fists now have guns. Is that a fair image or is it exaggerating?
Not really. Australia got a lot of props for reductions in violent crime when it put in it's draconian anti gun laws. Of course New Zealand in a very similar socioeconomic situation had the same exact violent crime reduction without any gun law changes.
Instead of punishing law abiding citizens for what criminals do, why not punish criminals harder, or work for social change that would reduce that threat.
I get your point. If we made it illegal in the USA to be gay or transexual, we would greatly reduce the criminal threats and acts against that group. They maybe suffer a little bit, but with thousands of attacks, I think it's for the better good right?
