Usually spoken of as Freedom of Expression now, to emphasize that more than actual “speech” is protected, Free Speech is still a source of much confusion. Here is a blog that highlights and clears up some of the problems. Essentially, the problem is that some people think Free Speech means that they should be free of criticism for what they say. I’ll let the Popehat post do the talking. Caution: their language is slightly more salty than what I use here. Not bad, but be warned. Here are a couple of quotes to whet your appetite.
“Only weaklings, cowards, and fools seek protection from criticism of their speech.”
“If you start talking about a ‘right to freely voice thought without the fear of public scorn,’ expect nothing but contempt.”
