People like Ted Nugent or my dad should not be impacted by new gun legislation, however, if they are known responsible gun owners, as Nugent might not be considered as such, I'm sure he's owned guns longer then most of you have been on the planet, and though he's very outspoken, he's also intelligent despite what his critics say! haha
My dad and brother hunt like many hunters do, they don't go hunting with assault rifles or pistols however, and the call for some armed defense is a logical one as well, though it might sound like trouble added to the mix, the laws regarding gun shows and screening of ANYONE wanting to buy or own a gun is a logical answer I believe.
In response to your points, sadly, I believe it is about guns and their intended use, as well as mental issues handled in the USA, or anywhere for that matter, WAR is an ABOMINATION in my eyes for such things, deadly weapons ultimately used to handle disputes, you can live though all that if resolved and solved in a manner without inflicting death, pain, or suffering, though there is always an unseen mental anguish in some capacity, we should always strive for Peace or your life is meaningless I believe, again, I think this is what all humans should do with their time on Earth
