Neither motorcars nor kitchen knives are intended to kill or injure people, albeit it is an unfortunate consequence of their misuse. Firearms, particularly the ones being discussed here are specifically designed to do just that.
I'm not a pacifist and hence I want our soldiers to have the best weapons available, but it is disingenuous to pretend that their weapons are merely neutral tools
No need to put words in my mouth - I never used the word "neutral". They are tools for hunting, pest control, sport, recreation, and even war. Tools for those purposes, open to misuse and abuse.
And that motor vehicles are not intended as a weapon is neither here nor there. They are frequently used as weapons to kill by terrorists, as has happened to terrible effect in Nice and London. Motor vehicles frequently kill through idiocy. Motor vehicles frequently kill through simple lack of attention and discipline on the part of the operator. Despite there having been 2 world wars, the Korean war, vietnam, 2 x gulf wars, the Iran-Iraq war, multiple pops at the Israelis, and dozens of other conflicts, the gun has still failed to come close to the butchers bill of the motor car. But that's OK, because the car driver (mostly) never meant it.
When someone is being lowered into their grave it's of no consequence to them that the car was never manufactured as a weapon - they're still dead. Be respectful around all items that have the potential to kill or maim, and don't be any less careful and respectful of the car because you simply happen to own one. Adopt a realistic approach to danger, not one based upon your clan membership. Trust me, if I were a loon I could kill a lot more people a lot more quickly in my XC90 than I could with my shotgun.
