Sure, I advocate possession of a car and airplane tickets. I personally advocate the possession of a weapon by EDUCATED, TRAINED, and/or otherwise RESPONSIBLE individuals.
However, the comparison of weapon possession to car possession is a pretty weak one. Sure, vehicles kill lots of people each year, but so does smoking. So does drowning. So, right after we ban firearms, we can go ahead an ban cigarettes, cars, and water. We'll lock everyone in padded cells. Absolute nonsense! Life is deadly. I don't know anyone who's gotten through it alive.
The difference is, most people NEED a car to hold down a job, get groceries, and survive. People NEED water to survive. But, 90% + of professions out there do not require carrying a firearm. These individuals do not technically NEED a firearm to carry out day-to-day activities, yet many choose to own one. This is either a good decision, or a bad decision, but either way it is an additional risk.
It is this "additional risk" that gets built into the S.O.P. safety examination. Sure, I'd be willing to bet you are a safe and responsible parent, but unfortunately it's our job to identify some pretty bad parents, and hopefully step in before things really go sour.
I apologize for getting you so worked up in the middle of the night, but I hope that you can see things from our point of view. I'd rather not have to ask those questions, but if I don't, my arse might end up as a defendant.
