I'm not a NRA-type. But I do like to shoot.
Not everyone here loves guns. And those who do love guns have hundreds of reasons why they do.
I keep a shotgun for shooting skeet. I don't care to hunt or eat birds, so it's just a sport for me.
I have a bolt-action rifle for hunting deer. I'm from the Southern USA, and deer season has been in my family since they got off the boat 400+ years ago. I grew up with it and it's something I love to do.
I also have a semi-automatic rifle. One could make an argument for it being an assault rifle, but just because it looks like a military rifle doesn't really mean anything. All semi-automatic rifles work the same. Again, this is a sport rifle for short and medium range shooting. A local gun club hosts a CQB tournament a few times a year and it's fun to run through their "village" and clear targets.
I also have a small, semi-auto pistol. It holds 7/8 rounds of .380. I use it, again, for sport. But I also keep it on me most of the time.
To most of the gun crowd, the 2nd covers any "gun" that fires any "bullet". We have people out here with everything from Civil War cannons to Vietnam-era artillery. Most people in that group agree that a tank would also be acceptable and I have heard that some people do, in fact, have functioning WW2/Vietnam tanks.
The crowd here gets divided when we start talking about bombs and missiles. I fly RC airplanes also, and I do a lot with tri-copters and quad-copters. Most of these control systems aren't much different to 80's style guided missile control systems. But folks around here just think it's going too far to actually implement such a system.
So, we stick with, mostly, a "bullet" fired from a "gun".
Yes, that includes rocket launchers, recoil-less rifles, and RPGs. There are several individuals in the area who are licensed to own fully-automatic weapons and RPGs and the like.
Really, in the US, it's all about what you can afford to license. If there was a "room-killer" on the market, then someone here would probably have a license to own one. I think it's a bit much for anything practical, but I still think it would be cool as hell to shoot one at the range.
A final point. The Second Amendment is a touchy subject. First off, there are (at least) 2 versions that differ in punctuation and capitalization. Second, people argue if it means a Military, a Militia, or just every-day people like me. No one really knows what "arms" are; could be a muzzle-loading smoothbore or could be a tactical nuke in the garage. Third, there is a lot of debate between "well regulated" and "shall not be infringed".
Anyway, it's all a dumb argument anyway. Most guns can't be obtained legally. The ones that can mostly need a State license. Even with the license and legally-obtained gun, you can't carry it in most places.
And that's the way all of the amendments are going. Somewhere, "Congress shall make no law...abridging...the right of the people to peaceably assemble" got turned into "free speech zones".
"The right of the people to be secure against unreasonable searches" turned into "stop-and-pat" and your iPhone doesn't count as "papers" or "effects".
Everything today is "interstate commerce" so the DEA can raid a local pot grower in Colorado.
The Second Amendment should have been a negotiating position to stop that from happening. Not so much of a "I'll shoot you if you try to do this" but more of a "let's see you enforce it" concept. That's probably what it was written for. But it's too late now and people have Idol and Game of Thrones to watch. It ended, not with a bang, but with a flurry of text messages to vote for the next Top Model...
