I accept your points relating to your stats, however, I do think that although rifles and perhaps pistols might have spawned from hunting animals, there is only one purpose for a semi-automatic weapon or the like.
IF (and I speak from a Victorian perspective) public transport was acceptable then perhaps you could make licensing harder as people could use public transport. For many, it really isn't a viable option, which is a problem.
Again, this comes back to minority. Gun licensing is tight (perhaps too tight from what you are saying) beacuse you are in a minority of people so it will only piss off a few, while make the rest feel vindicated. There have been many discussions on this forum about making licensing for cars tougher/retesting etc, but the problem is it would piss off too many bad drivers, who would (and should) not get/renew their license. The obvious solution would be for a political competitor to offer an alternative, and they'd be set.
Being in a minority can suck and makes some decisions seem ridiculous. Believe me, I have represented Australia multiple times in the sport of Olympic Weightlifting and like you I understand how being in the wrong group can mean you cop it. Unfortunately, I don't see it ever changing.
As for another minority (although less of a minority) smokers in Victoria have seen a steady decline in their freedoms over the years. I don't particualrly care, I don't smoke, but I have some friends who do and they can mount reasoned arguments against some of the laws here in Vic. But that's another matter I guess.
On a final note I would also argue that the reductions found in non suicide related gun matters (total of 53 over the ten year period) is well worth the hassle.
