Possibly, I simply thought about the incredible number of firearm owners I know and couldn't think of a single one who has fantasies about a breakdown in society or a hero complex.i think your number is probably a bit high.
I guess that all depends on who kicks in your front door. If three or four armed people broke into your home, I'm betting you'd understand why some feel the need for high capacity magazines.protecting family and loved ones (or hunting for that matter) does not require high powered military grade arms, or the ability to push high volumes of lead downrange in short amounts of time.
Further, if I may, let me add that unless / until everyone realizes that comments like 'high powered military grade arms' are emotional and quite silly in the context of what's available, we'll get nowhere. It's the same thing as those who constantly criticize Trump / Obama / whoever is in the WH - at some point, if you cannot speak in factual and unemotional terms when discussing a topic, you're only going to reach people who already agree with you.
Let me finish with this - I'm not unwilling to discuss magazine limitations, etc. I think they're pointless, but again, they may work - I cannot see what the future holds. But I'm only willing to discuss these sorts of compromises if both sides are willing to dial down the rhetoric and speak in facts.
Ultimately, we can point fingers all day, but those who wish to solve this problem via gun control laws need to explain exactly what they think needs to be done and how it will work in the real world. Working around 2A and the subsequent SCOTUS rulings makes that tough.
