I recently had a brief exchange with a fairly liberal friend of mine. He told me he took his daughter to a antigun rally in a state I won't name, designed to ban thirty round magazines.
"I don't think people should be able to shoot thirty times without reloading. You don't need that."
I remained calm and said "Well, I disagree. If I'm using a 30 round magazine legally why should someone else breaking the law restrict my rights? I have a few 30 round pistol magazines, so are those unnecessary too?"
"Yes you don't need those. What do you need those for?"
I need them for home defense because home invasions and armed robbery do in fact happen. And here's the thing, even with 10 round magazines, if I went bonkers and decided to shoot up a crowded building, I guarantee you that I could kill a similar number of people. Quick reloads are a basic skill of learning self defense, and if I have enough magazines on hand, I could do the same thing with one of my pistols. But not having to reload is a benefit, so if I'm not breaking the law, and am protecting my life, why shouldn't I be able to have a larger magazine? So what's next? Ban any semiauto firearm because a small portion of the population misuses them? Might as well reinstate prohibition and ban all privately owned vehicles if you're trying to save lives, because it's the same logic."
"Yeah, but you're normal."
I don't think I changed his mind, but he is a smart guy, and I could see the wheels start to turn. We were drinking beer too, so I changed the topic as the conversation was probably not going to end well.
