Phil Donahue was fired from MSNBC for having antiwar guests on his show. Even liberals weren’t allowed to publicly challenge the Bush wars too enthusiastically.

and:

“In July 2002, Phil Donahue returned to television after seven years of retirement to host a show called Donahue on MSNBC. On February 25, 2003, MSNBC canceled the show. Soon after the show’s cancellation, an internal MSNBC memo was leaked to the press stating that Donahue should be fired because he opposed the imminent U.S. invasion of Iraq and that he would be a “difficult public face for NBC in a time of war” and that his program could be “a home for the liberal anti-war agenda”. Donahue commented in 2007 that the management of MSNBC, owned at the time by General Electric, a major defense contractor, required that “we have two conservative (guests) for every liberal. I was counted as two liberals”.“

“Why do you hate America?” was such a common reply to any questioning of war fever that people started to say it sarcastically in reply to trivial disagreements.

When your mass media is owned by private corporations you have no free press you have a half dozen privatized state ministries of propaganda.
