It matters if you're actually trying to argue the merits of a given precept rather than try to claim "It's constitutional so it must be good".
Well I guess human history isn't logical, because that is exactly what happens.Nor does it logically follow one bit that overthrowing tyranny --> new tyranny.
All it has to be is superior to a minority of citizens to act as an enforcement of the regime.Rather bet heavy on the Milgram obedience study?
The bulk of the rank-and-file of both the armed forces and civilian law enforcement support the 2nd Amendment -- the actual, correctly interpreted by Heller understanding. How many would follow an immoral order to do mass confiscation and police the civilian population? Plenty I don't doubt. But would this be the most effective fighting force in the history of man? Or thoroughly demoralized and uncertain?
Again, history does not bear out your mythologised view of human behavior.
