I grew up in America as well. I haven’t encountered anyone who expected to own “weapons of war” either. No tanks or grenades for sale. No mortars, flame-throwers, or automatic weapons for sale either.
You see, there is a big difference between automatic weapons, which are illegal for private citizens to own, and semi-automatic weapons. There is a lot of false beliefs being pushed by those vehemently opposed to 2A and gun ownership in general. Most pistols sold today are semi-automatic, and they’re more commonly used in homicides, by far. However, AR style rifles look scary and more like ‘weapons of war’ so they’re the current target of the radicals seeking to strip the rights of millions of Americans because of the actions of a few. It’s called throwing the baby out with the bath water.
No amount of legislation will ever rid the world of evil, Larry. There are mentally disturbed people, there are immoral people, and unfortunately there always will be. The ideas around ‘red flag’ type laws deserve some further debate, however, it’s a really slippery slope. One thing is for sure, the current proposals take a ‘guilty until proven innocent’ approach which in my mind is off the table.
Who decides who is "mentally incompetent" as you say? Imagine this…two people are in a relationship. One of them is a gun enthusiast and loves to hunt. They have a bitter falling out. Knowing how much their guns mean to them, the non-gun owner, out of spite, goes to the police and says…they’re crazy! They threatened to kill me and they own all these guns, I’m scared! Please help me! So, currently proposed ‘red flag’ laws would immediately confiscate that person’s guns and force them into a long drawn out litigious process where they must prove their innocence. Is that fair and just?
Your analysis of the motivations for purchasing a firearm are pretty simple-minded. Disposable income and advertising? Just because you have no interests in shooting sports, hunting, or home-defense doesn’t mean the rest of us should have our rights stripped. Criminals don't obey laws. I hope you never experience a home break-in where you and your family's lives are threatened.
