Straw man. Your natural right to defend yourself and your home isn't at stake or at issue here. What you don't necessarily have a right to do is buy guns off the back of trucks in undocumented transactions, or amass arsenals in secret. Registration serves a similar purpose for guns as it does for cars - to assign a gun to its lawful owner for liability purposes, and to provide a basis for documented transfers and dispositions.
But it is entirely reasonable to require that you register your ownership and buy and sell your guns on the up-and-up.
You have the right to defend yourself. And the community has the right to protect itself from an unregulated market in guns. And you do NOT have the right to be a law unto yourself, and to pick and choose which of the community's laws you will ignore.
I see why most here have put you on ignore. You do have a right to accumulate as many guns/ammo as you deem appropriate. The fellow had 230 rounds of ammo, I have 10s of thousands rounds of ammo and want more. Heck, some 22 ammo comes in boxes of more than 500 and California thinks that is an arsenal. Some trips the the shooting range we uses more than 500-1000 rounds, good grief.
Defending oneself is more than just sitting at home, defending also means from a run away government. As described in the Federalist Papers (29), we are not just to be allowed pea shooters.
If circumstances should at any time oblige the government to form an army of any magnitude that army can never be formidable to the liberties of the people while there is a large body of citizens, little, if at all, inferior to them in discipline and the use of arms, who stand ready to defend their own rights and those of their fellow-citizens. This appears to me the only substitute that can be devised for a standing army, and the best possible security against it, if it should exist.
If going up against an army, you can sure as hell bet my thousands of rounds are just joke, yet you want to limit it. Yet team me up with like minded freedom loving citizens (like most other posters in this thread), we do make a formidable group to not be pushed around.
Private sales are another area we fully disagree. My elderly neighbor died, he left a widow that was sweet as honey (good Christian lady). We went to church together and we watched over her. When she got to age she was having trouble with her health, she called me down and asked if I wanted to purchase some of her late husband's guns (she had no children). I liked an old 20 gauge duck gun and just an old plinker 10-22. Gave her 100 bucks for each. You would have her purchase a gun license to sell them. Nope, she knew me, that I was no felon (against the law to sell to a known felon) and money and weapons exchanged hands. None of the damn government's business.
Most gun folks know that if someone is wanting to buy a gun and you don't know them, that you can go to a gun shop and do a ffl check on the sale (hope I got the abbreviation right). You can not do over state line sales without using a ffl, but making it hard for widows to get rid of their guns is BS in my opinion. If a widow woman does not know the value of her guns, she needs to impress the help a a church member (what I suggest anyhoo).
And the community has the right to protect itself from an unregulated market in guns.
Not at the expense of legal citizens which infringe on the second and God.
Shall not be infringed. Right now even the licensing of gun rights (CC permits) by Sheriffs is unconstitutional in my opinion. Renting the right that is guaranteed. Constitutional Carry should be the right of the people in every state.
