Nope not even close and if such is so then the Dixie Chicks have cause for A First Amendment case and trust me if such was so there would have been liberal lawyers crawling all over that one.
The First Amendment does not cover livelihood or talking on the radio it covers speech as well as freedom of religion and freedom of the press redress of grievances and the right to assembly.
So such is not a First Amendment issue and saying such just weakens the Conservative Movement and empowers the Left.
Stick to "what IS' and not to "what you WISH"...
And I'm still interested in the whole media matters angle (though I still haven't reached a clear conclusion). Here's an organization who's sole purpose in life (whether they admit it or not) is to harass, and, really, silence conservative political opinion. Fine, they're clearly not breaking any laws in the actions that they specifically take, but they're ability to function and perform these actions is clearly impacted by their available finances. Finances that are greatly impacted (improved) by not having to pay taxes. Seems like some kind of substance over form issue going on there.
