"Conspiracy Theorists"

Have you ever noticed that the second someone publicly discredits the government using their rights of free speech, they are automatically labeled as a conspiracy theorist? Whatever happened to the terms "philosopher" or "free thinker" to denote someone who ponders existence, the government, and how to improve upon it. We are no longer allowed to think freely and then share with others. If we do, we are labeled with negative terms that are usually associated with psychological disorders such as schizophrenia. You don't think that the government has your best interests at heart? You MUST be crazy!
