Net-net, the ad should not have been banned. By banning such a passive ad that simply states that a church is open (even though I think it is deceptive as the church is more than just open), is a travesty of censorship by the networks.
It is NOT simply stating that they are open to all. It is simply stating that all other churches are open only to white families! When was the last time you were in a church that had NO Blacks or Hispanics because "they were turned away at the door by a bouncer"????
Maybe we should all attend a UCC service in our wicken apparel, or our terrorist burkas and suicide bomber belts, or wear hunting camos and carry a sign claiming homosexuals deviants!
If the UCC is open to everyone...
