The closing paragraph from your link
The best way to demonstrate the hidden influence of the chosen people would be for Jon Stewart and others to join me in calling for Rick Sanchez's reinstatement. If it then didn't happen, it would help us understand who really pulls the strings around here.
I don't think Sanchez was fired for what he said about Stewart. I think he was fired for his rant about not being seen as suitable to be an anchor -- not based on his abilities, but based on his ethnicity. That's always debatable -- why did his boss liken him to an hispanic reporter if it wasn't about his name/background? CNN, as of yet, hasn't made any comment on why the let him go.
Glad to see in tsar's link that Sanchez and Stewart have spoken.
