Our country was born of the fires of rebellion, and if the spirit of rebellion is not kept alive then our government shall have nothing to fear. Governments are made up of people and should not be an omnipotent power. As Thomas Jefferson once said, "The two enemies of the people are criminals and government, so let us tie the second down with the chains of the Constitution so the second will not become the legalized version of the first."
What he means in saying those words is that Government is an unnatural but necessary concept, and when left unchecked will turn and commit crimes against man and his liberty without anybody in a position to stop it. The Constitution was meant to chain up the government, to imprison it to prevent this. But when we give the government the means to take away rights of the people, it is like giving a prisoner a file with which to remove his chains. Now left free to itself, the government could commit crimes against liberty and nobody could be in a position to stop them.
I say keep all the rights of the people in place, and never take them away. Government is unnatural, and should be minimal at best, and to keep it that way the people should have means to rebel if necessary.
