It's teaching them atheism (among other things) with blasphemous songs like this one. Don't underestimate the potential for your children to become corrupted and their faith in God wrested away from them by the popularization of atheism through things as simple as songs and videos. If you have MTV and its affiliated stations coming into your home, cut it off now. Don't wait. Don't dither. Don't accommodate this malignant evil even for another second. And let's also all take a moment to pray for the deluded atheists who produced this song and all those whom it is affecting.
