The dawn of a grave era in free speech is approaching. The era in which ideas, opinions, and expression can be blinked out, shortened, and ultimately controlled by people who push their own ideals. Now we must watch what we say, do, and even think, as people are ready and willing to link unrelated issues together in futile attempts at clairvoyance of ignorance. The 1st Amendment of the Constitution gives every citizen the right to free speech, expression, religion, protest, etc., but everything must be in bounds of the law. Uncovering the flaws of a system or person while including labels and opinions isn't illegal.
Children do it all the time to one another verbally, as do adults.
Written statements using slander against officials or people are protected against and by the law. If I can write an article in a published newspaper with millions of readers saying the president is scum and unfit to be in office, more power to me. Not only am I expressing my opinion, but doing so is protected by the law. Certainly it can be hailed as its demise. When fellow people call out other people and pull finger-pointing routines whining and crying about how so and so made my reputation fail, it's clearly a serious matter.
