This is as much of the Congress proposing a Constitutional amendment to replace the 2nd Amendment as there is of it proposing one regarding abortion. Besides, such an amendment would be limiting the Congress's authority. Other than the Bill of Rights, the only amendment that limits the Congress's authority is the 27th Amendment (proposed along with the Bill of Rights).
If the Nine High Priests Of Justice give the 2nd Amendment a "collective right" (i.e., nullifying) interpretation, then our choices will be:
(1) Quietly defying all gun control laws,
(2) Acts of Civil Disobedience (open defiance),
(3) Start a movement to call a Second Constitutional Convention that would propose a new RKBA amendment,
(4) Revolution/Rebellion/Secession.
This sentence should have said:
There is as much of a chance of the Congress proposing a Constitutional amendment to replace the 2nd Amendment as there is of it proposing one regarding abortion. The portion in italics is what should have been in the earlier version of that sentence. As stated in an earlier post, this site needs an edit button.
