It was a joke, but I have no reason to believe that the threats I was responding to were jokes.
What threats would those be?
The threat of a free man going about his life without a by-your-leave to you? That threat? It is good that would-be tyrants feel threatened by that. It keeps them from trying to become real tyrants.
As for your whining about my alleged death threat, America is imposing Rule 7.62 on the enemies of freedom around the world, even as we speak. If you feel threatened by a reference to this great land's armed forces and their mission of defending liberty, then maybe, good sir, you should be in a cell with your buddies Achmed and Abdul, down in Gitmo.
