The 2nd will outlast the NYT.
I suspect that Justice Stevens has forgotten the circumstances surround the passage of the 2nd amendment and the entire Bill of Rights.
The Constitution had failed to be ratified with limitations on the new government. Ratification was only possible WITH the concurrent passage of the Bill of Rights. I suspect that if the Bill of Rights is attacked it will unbind the colonies.
I could be wrong, but I hope we never have to find out! The consequences would be devastating.
