If that was true, we should have the right to bear NUCLEAR arms (otherwise it's going to be a pretty one-sided battle!)<quoted text>.
The reason we have the second amendment is so we can defend ourselves against a hostile govt.
Actually, the text of the amendment says the right to bear arms shall not be infringed, but the Supreme Court has ruled that that, while the right exists, all sorts of limitations are legal. That sure sounds like "infringement" to me.
