"Do we cherish the right to bear arms because it’s in the Constitution, or do we cherish it because it is logical and moral? Do we cherish free speech and the freedom of religion because they are in the Constitution, or do we cherish them because they are also logical and moral?"
We support them because they are logical and moral. We support the Constitution because they protect these rights.
“It is not our part to master all the tides of the world, but to do what is in us for the succour of those years wherein we are set, uprooting the evil in the fields that we know, so that those who live after may have clean earth to till." -J.R.R. Tolkien
