What is it that compels 'liberals' to always attach the blame in exactly the wrong places? It is ridiculous to blame inanimate objects for murder, as if they had minds of their own, that compel them to take human lives. You are giving the instruments used in conflict supernatural powers...do you also believe in ghosts and witches?
Here's some news for you: people get murdered with knives, baseball bats, and motor vehicles, every day. Do these objects also have this supernatural ability to select innocent humans for destruction?
The proper use of a self-defense firearm is to enable a weak person to protect himself from a strong person. Why are you opposed to that? I suppose that Canada is so much more civilized than the US that you can simply not even conceive of being attacked. Congratulations with that, and good luck for the future, because you are out of luck if some evil bastard goes through the victim selection process and it spits out your name.
