Joshua Marshall has already dissected the highly tendentious claims by CBS as to why it would not run the innocuous UCC spot advertising diversity.
Now Pudentilla points out the naked hypocrisy of the network's decision. It turns out the network had accepted a pro-diversity campaign by the Methodists in 2001. The only difference was the Methodists didn't include gays pictorially, whereas the UCC ad did.
Had CBS changed its policy in the meantime? Possible, but unlikely. Which brings us back to the network's claim that because the president has proposed a constitutional amendment to ban gay marriage, it cannot run an ad which says a church welcomes gays. Leaving aside the bizarre policy itself, which Marshall and Pudentilla and others discuss, what is revealing is the leap taken from the question of gay marriage -- an important but discrete topic -- to, apparently, any mention or implication of gay people whatsoever.
(Finally, as Pudentilla reminds us, this is the same Methodist church that yesterday defrocked a lesbian minister.)
