The politicians are always working on tweaking freedom of speech because political correctness has turned out not to be oppressive enough. They use back doors and side entrances to attack freedom of speech, because if they came in the front door, you would know what they were up to, and you would use your freedom of speech to stop them. The political leaders tell you their actions against your liberty is for your own protection, because apparently you can't be trusted with it.
