...I don't want some yahoo without training being able to OC a firearm"
I'd venture to guess that this person feels that they are not competent with a firearm, and therefore assumes that the "average" person is not. They don't trust themselves with a firearm.
"What's to stop someone from shooting each other over a parking spot if everyone has guns?"
I'd assume this person has their own anger problems, and believes that they themselves might become violent over a petty argument if the tools were available. Because they feel this way, they assume that the "average" person does, too. They don't trust themselves with a firearm.
"Having a gun around children is just asking for trouble. Accidents do happen, you know!"
I'd bet this person is irresponsible, and tends to mislabel their negligence as "accidents". They're probably not responsible parents, either. They think the best way to protect their children is to remove anything that may hurt them, instead of educating them and raising them properly. They also assume that the "average" person is just like them. They don't trust themselves, or their children, with firearms.
It's become more and more obvious to me that almost any anti-gun argument can be brought back to a lack of safety, responsibility, and self-control on the part of the anti. They don't trust themselves, and so they don't trust anyone else. That sounds like a scary world to live in.
