Their campaign is called "God is Still Speaking" and CBS and NBC have refused to air it because it's all about the UCC's opennes to people of all races and sexual orientations.

"Because this commercial touches on the exclusion of gay couples and other
minority groups by other individuals and organizations," reads an explanation from CBS, "and the fact the Executive Branch has recently proposed a Constitutional Amendment to define marriage as a union between a man and a woman, this spot is unacceptable for broadcast on the [CBS and
UPN] networks."

So CBS openly admits that the President's agenda now determines what is acceptable for broadcast on their stations. Have they no shame?
