Its the difference between GOVERNMENT restricting speech and society influencing it. One is against the constitution, the other is not. And I assumed you were just making the shiite up about death threats.
The Chicks got death threats. And you said that was just people "exercising free speech."
The secret service was w/in their rights to talk to Nugent - his comments were a veiled death threat, by any measure.
Last, I have never suggested, nor would I suggest, that people don't have a right to boycott the Dixie Chicks. I just think it's kind of cowardly & unAmerican in spirit - that's my opinion, which I'm expressing.
