A little reported event occured this weekend that should have the attention of every American. Congress actually debated revoking your right to self-defense. No, they didn't offer an Amendment to the Constitution; they instead sought a way to bully states into striking down "stand your ground" laws having the same outcome without the due process.
Self-defense is a natural right. Period. There is no legal debate to be had here. Self-defense is also a moral act as individuals have a duty to avoid harm and preserve their lives which in some unfortunate situations requires a level of force. Pragmatically, self-defense is necessary in a civilized society as a means of de-incentivizing crime via natural consequences. And the collective benefit of such acts is demonstrated when comparing crime rates in populations that acknowledge this natural right v. those that do not. It bears repeating that America's crime capitals have the most gun control.
