Super Bowl Commercials

Every year, we all gather around our own or someone else's television set to watch the Super Bowl. Even if our team finished on the outside looking in, we still come together to watch the game. Why? The commercials. Everybody loves Super Bowl commercials. This year there was a bit of controversy surrounding a few of the advertisements. CBS refused to run an ad for a male homosexual dating website (I can't remember the name of the site offhand) because it was too provocative and presented a strong point of view on a controversial issue. However, they allowed a commercial from Focus on the Family, a Christian ministry organization founded by James Dobson, to run. The premise of the commercial was to present a pro-life stance on abortion using the story former National Champion and Heisman Trophy winning quarterback Tim Tebow and his mother. Now regardless of mine or your point of view, my question is, should the ad have been allowed to run when the homosexual dating site was rejected? It is still a controversial issue with political, sociological, and religious implications and I'm sure most people who saw it had a strong opinion one way or the other. Why would CBS allow this ad and not the other one?
