What's the Biggest Threat to Free Speech?

I would also add that it's those who would seek to force political commentators off the air through tactics such as getting their sponsors to abandon them. I vehemently, disagree with the likes of Ed Schultz, Keith Olberman, Bill Mahr, and others on the left, but I will fight to the death to protect their right to give their opinion. Those I do not like or agree with, I simply do not listen to!
