I shot my 'first' gun when I was 9 years old while in the boy scouts. Gun Culture is in my blood. You sound so intolerant and closed minded. Perhaps you should visit a firing range someday and see what that culture is really about instead of basing your opinions on ignorance.
I know plenty about guns without having seen them. We own several. We simply don't keep them in the house. Maybe you should just as equally consider looking on the other side, because America is a huge joke with the amount of guns and gun violence running rampant down there.
I don't really have a problem with weapons. I have a problem with weapons in the hands of people who shouldn't have them, because they (the person) is dangerous. But I'm pretty sure most people feel that way.
The only real issue I have with guns at ALL is 'swift immediate justice' when it isn't needed. That is, shooting someone you THINK is a threat who actually isn't. People don't always act rationally. Yeah, it's one thing to shoot the guy with gun who is killing kids at your school, totally a different story to shoot some kid walking down the street because you 'felt threatened'.
That's the whole reason we have the justice system, to avoid killing or punishing (more) innocent people.
But I'm sure when you look at it as a total, the number of people who are wrongly shot and KILLED is probably pretty low.
Paranoid people don't need guns. They need....I dunno. Phasers that never go above 'stun'. Yeah.
I'm down with having an armed security guard at a school. I mean, hell, there's always an officer hanging out at my daughters elementary school. And most of the high schools around here have either armed security or police that are paid to be there.
I don't think teachers need loaded weapons in their desk, but I'm fine with SOMEONE armed. I'm fine with teachers keeping non-lethal weapons or SOME of them having working firearms.
I don't think all of them should have firearms, but really that's more of a self control and control of the class thing, I know some kids that would make me want to shoot them in the face sometimes.
At my high school, half the kids had hunting rifles in their trucks all the time. I didn't worry about them OR the safety of the school (though of course someone would have had to sneak out into the parking lot to get them if there was an emergency).

That is what background checks are for. As long as the handlers are properly vetted through the concealed carry permit process there should not be problems.
The point is someone should have the means to defend themselves. No single entity should have a monopoly on the power of safety. If an authority figure starts killing people the answer is to shoot back and defend yourself. The plan of arming teachers is still the most sensible and reasonable solution in every one of those situations you linked.
