The Supreme Court has already ruled the 2nd can be infringed as written. The only real argument is how and how much........same as the first amendment.....how do you define pornography that has already been ruled to be infrangible.Not if you do some research as to the intent and purpose of the existence of the 2A.
You can have the opinion that the 2A needs updated, and like mentioned, there is a way to do that, but as written, "infringements" on "arms" are unconstitutional for "the people".
