As I pointed out, our representative government clearly has the authority to determine who is allowed to own what items and what other items are illegal to posess, whether they are weapons or not. The authority is there, whether you believe in it or not. Refusal to obey the authority will get you thrown in jail. It's the way governments work, because by definition, every government is tyrannical. The only truly free men are those who have no governing authority (i.e., a true anarchist society).
We, the people, give this government the power to do this. Maybe not you specifically said "I don't want anyone to have full-automatic rifles," but there are other people in this society that did say that, and that want their say in the way the government works in other aspects, too. Is this a bad thing? Depends. The world would be pretty boring without the Left v. Right thrust in constant bipartisan debate.
If we were allowed to own full-automatic weapons, would everyone be happy with that decision? Absolutely not. This is where we come to a little thing called, "a compromise." The representatives from the people compromised and decided that some weapons would be banned, but that it wouldn't be fair to take away all weapons. So now we're in this are we the Pro-gun people are happy we still have guns, but sad because we don't have all the guns. The Anti-gun people are happy some of the guns are gone, but sad because they didn't get rid of all the guns.
So you ask who has the authority to determine who gets what and why? Me and the rest of the 295,734,134 people who live in the United Sates, through representative government. You're part of that. Want to be heard above the rest? Then do
something. Posting on a forum and arguing with me about whether government authority is real or not doesn't count as "getting the word out."
I was trying to make the point that no one has the authority to decide what types of weapons I'm "allowed" to own.
No
one has the authority. The authority comes from
"We". Now I know there are some people out there thinking, "If the government doesn't have authority to take my home-modified unregistered silenced full-automatic 10 inch barrel AK-47, then they don't have the authority to throw me in jail." This has been tried before. You see, we had this little thing called the "Eighteenth Amendment" which banned the sale of alcohol. Some people didn't like this, it was "unconstitutional." So what did they do? They made their own alcohol anyway. When they were discovered, they were thrown in jail. It doesn't matter that the "Twenty-first Amendment" made alcohol legal again. Those people who defied the law were still criminals, some of them were still in jail, and the past had already done it's damage. The law is the law, whether it's right or not, whether you believe in it or not.
