I agree with you about it depending on who owns the gun. But at that concert there apparently were at least two bands playing who were gun owners (John Rich and the previously mentioned band who said their guns would have been useless in this situation), and both of those gun owners thought rationally about whether or not to use their guns.
I don't know why people have gun fetishes, must be something within our nature. But the backhoe comparison doesn't really work because there are most certainly farm shows with this type of equipment.
If only gun shows were as unsexy as farm shows.
Gun shows would only ever be attended by professional law enforcement and military sorts, and everyone else would consider them a big ol' yawn.
I don't think the gun fetish is in our nature.
I've been thinking about this a lot today. What makes Canada and the US so different? We're similar in many ways. We've had our own (much smaller) mass shootings. We have a lot of gun owners. But our gun crime rates are significantly less.
I lived in the US until I was nine. Gun toys were banned in my home. Like any other American child, I turned every stick into a gun. And I promised myself that I'd never forbid my children from playing with toy guns. It was fun, and it seemed natural.
My children were born in Canada, in an urban area. They turned every stick into a sword. They never showed any interest in playing with toy guns, and neither did their friends. The only time I ever saw them play at having guns, was immediately after I showed them some old original Battlestar Galactica episodes. But shooting imaginary bullets was apparently not as fun as beating each other with sticks. The whole "do we allow toy guns" debate, was never a debate in my home, or any other family's that I knew.
I don't know of anyone in my city who keeps a gun in their home, though I know many who have guns at clubs, where they use them for target shooting and sports. In rural Canada, many people have long guns in their homes for hunting or protection from wild animals. I know some of those people, too.
Guns are largely viewed as tools, kept for practical purpose.
It's not nature. It's nurture. And, as such, it can be changed!
