If you feel you need to carry a gun, by all means carry one. I'm not telling anybody NOT to carry. You are getting extreme views on both sides of the fence here... it is up to you to process it. Maybe if it was legal in Canada to have a CCW, I would... who knows? But perhaps because it is not so readily available, I have found alternative (and effective) means to protect myself and my family in the wilderness. The OP did direct this thread to "wilderness animal attacks and predators".
You have every right to view bearspray as ludicrous. Just as I find it sad that folks view the wild as an "adversary". It has its dangers, but if you learn how to live with it, you can negotiate the obstacles. I have said it before, "Knowledge is the fear killer". Increase your awareness/understanding and decrease the risks.
As for the clothes, fire making, FAK, shoes analogy to protection... that works fine, just don't forget the climbing gear, flare gun, PLB, tazer, helmet and body armour the next time you go out. Infact, do you drive a motor vehicle, cook with a gas, take an elevator, swim in the ocean, drink alcohol, smoke cigarettes or read in low light? Its funny how the mind can often times "cherry pick" dangers or insert false fear where there is none.
Fear makes people do a lot of unnecessary things. It also has a way of propagating itself and leeching into all aspects of your life. Don't let it rule over you and don't allow the fear mongers paint the portrait of your life for you. View the facts and make the descision for yourself. Gun or no guns, it really doesn't matter to me what you choose.
