Aggressively killing everyone is the only way to successfully defend democracy. If anyone lives, there is a chance they will attack democracy.

Why is the U.S. called U.S.A.? Any state can join the Union. What's wrong with the U.S. anyway, that they think it's ok to go around murdering innocent people and claiming their crimes are 'in defense of democracy'? I've got a great idea, let's all do whatever we want and then simply claim our actions were in 'defense of democracy'. Apparently, if you say your actions are 'in defense of democracy', you can do anything you want.
