When the 2nd Amendment was written, were Gun rights included to allow citizens to protect themselves from each other or the standing government?
There are no gun rights in the 2nd Amendment. You misunderstand the purpose of the entire Bill of Rights. The Bill of Rights doesn’t grant rights.
The founding fathers believed strongly that every human being possessed certain fundamental rights. They have them. They don’t need a piece of paper to say they have them. The Bill of Rights is a written guarantee that the government won’t infringe on those rights. It doesn’t allow me to do anything. I can already do that. It says what the government can’t do.
I have the right to defend my life and my freedom. From whatever threatens it.
