In response to MattyScornD's comment:
The type of acute paranoia that would lead someone to hoard assault weapons seems pretty close to a mental illness, to me.
Various forms of alcoholism and drug abuse should also send up red flags and spark some debate about who has the guns and what they may do with them. PTSD from serving in combat is another diagnosis that doesn't really square well with gun abuse.
This is not really nor ever been about the guns themselves; it's about the morons and mental defectives brandishing them.
I agree and you must not let the acts of a few restrict the freedoms of the many!
BTW: you call hoarding what some call collecting.
Are you a coin or stamp hoarder?
The ability to blow someone away isn't much of a freedom. Gun ownership is both a right and a privilege. A right because our constitution partially provides for it; and a privilege because of the power inherent in the hand that wields it against someone who's unarmed.
Hoarding, collecting...same difference...usually it points to obsessive-compulsive behavior which, in some people, can manifest itself as a serious mental disorder. If guns are really just tools, then what do you need 200 hammers for...?
Not all guns are the same. So it's not the same as having two claw hammers. There are handguns, rifles, shotguns all giving different shooting experience. If one likes to target shoot and hunt then they would want different guns. Depending on what they hunt they'd need different rifles. You wouldn't use a gun used for killing moose to kill rabbit or kill turkey.
You also wouldn't target shoot with a deer rifle as the ammo is expensive. So one would have a handgun for that. Or maybe a .22 rifle as .22 ammo is very cheap. With handguns one might like to have a big caliber and small caliber. Especially if one wants to teach their wife or kids to shoot. New shooter shouldn't start out with a .44.
Some may like the look of old west style guns and want a single action pistol or a Henry lever action rifle for fun target shooting.
So depending on what you're doing one would want a different type of gun...not unlike a carpenter needing a different type of hammer depending on what was being done...claw, ball pein, club, sledge, joiner mallet, framing, soft-faced, etc.
Millions of gun owners have multiple guns without ever an incident.
I would say the same about someone who hoarded cats and didn't take care of them properly lest they spread disease.
As far as the "freedom of the many", nobody's "freedom" is adversely affected by background checks.
