The comedian resides in a privileged realm. As long as he can defend his words --or make them mean nothing-- he can say anything he wants.
His most powerful weapon is the truth. No one will challenge him on its utterance. And his enemies scatter at the sight of it.
The reason why I can openly talk about the wholesale executions of members of the now defunct United States government is because everyone knows it's true.
The only escape from execution is redemption. And redemption comes only from oneself.
