My only real complaint with the discussions I've had on the topic are that people who prefer firearms over bear spray downplay the effectiveness of bear spray in direct conflict with the available evidence. They often use language that suggests your are taking an unreasonable risk if you choose bear spray as your primary defence tool in bear country, and yet all the available data suggests that it is your safest bet.

If a bear charges you, you have a much greater chance of being injured or killed if you try defending yourself with a firearm than if you try defending yourself with bear spray. This is what the facts from multiple sources all say and I've yet to see any substantiated argument to suggest otherwise.
