It may seem hypocritical but there are things you don't say in front of your mother or in front of the children. What he said is permissible on HBO or Comedy Central or even the Disney Channel because cable channels are presumed to be "paid tv" so women and children choose to be subjected to offensive material. The over-the-air channels, such as CBS, NBC and Fox are held to a higher moral standard because their locally-owned stations make their living over the public airwaves and must regularly apply for rights to get or keep using certain over-the-air ratings.
That's why Janet Jackson's infamous "nipple slip" at the Super Bowl generated fines because the Super Bowl was being shown on over-the-air television while the same thing or worse can be shown on MTV and nobody would complain.
Colbert deserves to be fined and so does CBS. It was offensive and it is presumed what goes out on his type of show are scripted and rehearsed so, therefore, not accidental.
What would be funny is to see how the liberals would do a 180 if the same thing were said of Obama or Hillary Clinton by a conservative comedian.
Do you know a conservative comedian?
Colbert’s departure also reminds us how hollow conservative comedic efforts have been, as they fail to play catch-up in the cultural war of political satire. Humor remains a rhetorical weapon that American conservatives simply cannot harness.
