This was an interesting post title to see on the front page of NSMB, to say the least.
I'll attempt to give a different point of view on this topic. Brief background: I'm mid-30s, grew up as a "country boy" in the US, military vet, politically I'm a slightly left-leaning libertarian (F#&K Trump; Tulsi 2020). I've traveled around the US, Canada, and Europe, and would gladly live in BC if property prices weren't so crazy. I've also been spending time deep in the PNW forests for my entire life.
In the western US, there are areas that get remote enough that you can run across people who don't want to be seen. I've encountered a handful of questionable situations in my life... sketchy drug operations and users, unhinged individuals who aren't happy to see you, people foraging for very valuable plants, etc. The odds of these types of encounters turning violent are small, but they exist.
Luckily 95% of MTB trails don't get this deep in the woods, and the traffic that our trails see discourages the aforementioned sketchy people from being near the trails. I never carry a gun while riding, the risk isn't there and the weight isn't worth it. But if I'm hiking, camping, exploring, etc, and I'm straying further and further from civilization, you bet I'm [legally and safely] armed. When you're 20+ miles away from the nearest town, have no cell reception, and can't rely on a PLB for any type of quick response, you have to weigh the odds of self-defense versus the risks you're taking.
A larger aspect is the American "gun culture" which is... significant. Our country was designed to give citizens self-reliance and power over the government, which was the primary motivation behind the Second Amendment (anyone interested should read the Federalist Papers for background and clarity on the intent behind our constitution. Our Founding Fathers would be appalled at the idea of America having a standing Army, and the federal government wielding power over the populous). While many urban areas in the US have abandoned this ideal, a huge majority of areas (by square mileage) depend on self-reliance to thrive and prosper. America is definitely at a crossroad between the wants/needs/desires/ideals of the urban populations versus the rural populations, as seen by our political soap opera of the last 8 years.
So yeah, this topic will absolutely be crazy and foreign to Canadians. Your country is generally safer, your people are generally nicer. You also happily have a fairly liberal (and very functional) Constitutional Monarchy for government, which appears to be indicative of Canadian ideals from what I've experienced.
I'm drinking tea and eating scones for breakfast today, I think I'll get back to that.
