Why aren't conservative Christians outraged by this ad?

[Santander]

Don’t only Catholics sing that (awesome) song, anyway?  That’s, like, not even close to a majority of Christians, if it is truly a Catholic tune.  Might explain them not caring.

Um what?

People other than you understand culture and taste.

I listened the ad, it barely sounds like music. Like the piano part at the start is OK, (like the song at the beginning of Mellon Collie and the Infinite Sadness), but those vocals, OMG WTF.

I'm at a train station right now and I seriously almost threw myself in front of a train after reading this.
