Karl Marx said that the total control of communications is an integral part of bringing about his totalitarian state to ultimately bring about his society that is totally conforming and egalitarian. Rising dictators throughout history have always taken control of the communications and gathered information on the citizenry.
The argument today is that it is critical the government have the right to gather information to protect the citizens from terrorists and the like. This argument does have appeal. All Americans, except those who would commit acts of terror want the government to stop terrorist attacks before they happen. This is the same argument that has been used by rising dictators throughout history. Just like the takeover of medical care and coverage was purported to be for a good cause, we quickly learn the end result does not accomplish its stated goal but is used for other clandestine purposes.
When an American says he has nothing to hide because he has done nothing wrong he thinks he is living in a country that has no motive but to have a free society. Citizens of other countries who believed the same way have learned that the meaning of those who would do evil and what is wrong or right is determined by those in power.
We have been told the typical American citizen commits at least three crimes every day. A government who has a “Main Core” list will use the information gathered to put away any citizen it deems unacceptable. Many an honest and law-abiding citizen has found they can be punished, even when they do not break a law. Martha Stewart is a recent example in the United States. She was found innocent of insider trading, the crime for which she was indicted, but then went to prison for supposedly lying to the government. This is what Justice Departments of tyrannical and aspiring governments will do. This is why it is so important your privacy be protected. If you are considered an enemy of the state right now by the current Marxist/Progressive regime and Holder wants you put away, the evidence would be available to put you away.
