Ha. "Agreed" only in the most superficial way. You might have caught people saying it occasionally.
If you follow civil liberties debates and the politics thereof you know there's often a gap between what politicians (or just ordinary people) say about freedom of speech and what they actually believe and do. In the US the politics of things like compelling public schoolkids to recite the Pledge of Allegiance, to give a perennial example, are illustrative of this. (there are tons of examples involving obscenity laws, etc.)
