Holding the opposite really brought discredit to the rule of law. People began to see the ever more nuanced and convoluted opinions in the 4th, 5th, 6th and 8th Amendment cases proscribing Government mischief and leaving the clearly written 2nd Amendment as a nullity as clearly Judicial Tyranny, to be twisted by whatever Activist Judges are currently on the High Court.
For its own respect, and the Rule of Law, a way must be found to harmonize Constitutional treatment of ALL the Bill of Rights.

In 1868, the 14th amendment was ratified for expressly that purpose, -- and has been fought against ever since.

The fight to incorporate the 2nd is starting. -- That's what the Ashcroft 'decision' is all about.
