Mistakes

Chesterton: The business of Progressives is to go on making mistakes. The business of Conservatives is to prevent mistakes from being corrected.

And when Conservatives are allied with the Progressives as happens from time to time (the initiation of the public school system - designed as indoctrination centers from the beginning, the Drug War) things get really bad.

What do both Conservatives and Progressives have in common? They both believe that there is nothing you can't accomplish if you have control of government guns.
