Re: "Second Amendment is obsolete"
The purpose of the Second Amendment is clearly stated in the preamble to the Bill of Rights - specifically “The convention of a number of states having at the time of their adopting of the Constitution, expressed a desire, in order to prevent misconstruction or abuse, of its powers that further declaratory and restrictive clauses should be added”. Note that when the Second Amendment was written, every weapon was a weapon of war, there were no restrictions on the private ownership of weapons and the militia was equally matched with the regulars. For instance, I’ve never seen it said that the regulars could carry 30 lead balls but the militia could only carry 15. After all, if they weren’t equally matched, it would be pretty hard to deter or prevent a “misconstruction or abuse, of the government’s powers” - so in reality, the citizen militia of today should have the same firearms as the current US military.
