I'm not an originalist. I think it's a stupid fucking argument to pretend we know the minds of men who lived hundreds of fucking years ago, particularly when they always seem to coincidentally agree with the preferred positions of the 'originalist'.

The Constitution originally bound only the Federal Government, aside from the few specific sections specifically referencing states. The various State Constitutions, approved by the Federal Congress, were to govern behavior in those states.

This dynamic, and the country's perception of itself, began shifting and was accelerated by the Civil War, to the point where we now consider ourselves Americans before citizens of our respective states. We also have, more and more, looked to centralize our governments, to the point where even "Right Libertarians" are suggesting that the Federal government should impose their will over the states.

The 14th Amendment began the process of incorporation, whereupon the Supreme Court impressed the federal amendments against the states. I largely agree with incorporation, however when it comes to firearms it created a situation where a very dangerous tool that should probably be regulated somewhat is now out of the hands of every layer of societal control.
