Uh this is just hilarious, I don't even really know where to start.
Since I am feeling nice I will point you to some things you can read to enlighten you. On the rights front, you might want to start with
Heller and
McDonald to see two standing cases in which SCOTUS laid this question to rest. To summarize, 2nd protects an individual right to bear arms and this right is incorporated (ie it also applies to states)
PS: Could you show me the section of the US constitution that deals with an amendment going out of date in other way than a new amendment? I would love to see your sources.
