Well. Since the tools are lethal, and countries implementing the death penalty always end up killing innocent people, and more guns = more gun violence and accidents, it's obvious to me that these tools are not safe. To me, gun safety is as applicable to the real world as the perfectly straight line in mathematics, or the perfectly rational thinker in logics...
I'm fascinated by the emphasis on protection in your (and Americans' in general) definition of safety. In Europe, "safe" simply means "not dangerous". From your "~~wildly~~ widely (edit: typo) understood" definition, I get the feeling that you view danger as unavoidable. Would you mind sharing your thoughts on what safety would mean to you and your community, if there was no danger to protect from? Would you still carry a gun for protection if all strangers were harmless? Have you ever visited a country where no one, not even law enforcement, carries lethal weapons? Etc.
Yes but the reason I don't agree with you is that knives, and cars for that matter, serve different purposes:
Do you not see the difference here?
