This is definately a fair point.
But what about systematic avoidence of contraversial issues by writing off the supporters? I mean, obviously, it's still protected, but what about the effects?
Would you accept that if the media systematically uses rhetoric that is intended to discredit supporters of a given cause, it will effect overall opinion, and the extent of this effect, if left unquestioned, could, in the right situation, be limitless?
Would you also accept that to seriously threaten our first ammendment rights first you need the public in support of a fringe issue that would stake them in support of taking away those rights?
And if you accept both of those, then wouldn't it be reasonable to believe that the systematic use of rhetoric with the intent of discrediting supporters of a given cause could be a threat to our first ammendment rights?
I'm not saying that I neccisarily believe that this is a real substantial threat to first ammendment rights, but I am saying that it's a reasonable thing to believe, if you accept those beliefs.
