Remember how it was immediately after 9/11 ?
The Repubs and especially Bush and his criminal side-kicks didn't want to hear and conspiratorial comments. Furthermore, US and other world citizens took the chance of being Arrested in the middle of the night and Incarcerated for who knows how long, simply for speaking out against Bush.
Finally, to all those Republican/Conservative mental cases out there .. and in the fine words of Bill O' the Clown ... Just SHUT UP !!! The whole planet thinks you are all completely retarded.
