You mean besides the obvious?
The argument was never that people don't get killed by means other than a gun .. that would be a stupid argument, would it not?
The argument is the relationship of lots of guns to murder by people known to the victim, suicides, accidental child shootings, protection, the 2nd Amendment, and legal shootings.
If you'd like to continue to use Canada to validate your point on that argument, be my guest .. but of course, you aren't going to use Canada because you'd then be making my argument, not yours.
That being said .. those who want guns, let them have them .. they're pretty much killing themselves and their families anyway. The down side of it is gun-lovers are the criminals best suppliers for weapons.
