Personally:
No, Yes, No; with reservations, Yes, Yes and Yes.
Plus, unrelated to SoJoCo’s question I HATE the title of this thread. People have rights, states have powers, and inanimate objects have...well, nothing they just exist.
Then if we can agree that the right to own a firearm should be as restriction-free as possible but still is not an absolute right, then shouldn't the states be the ones deciding when and upon who that right should be restricted and not the federal government?
