Okay, these kids probably don't actually hate music. But their callous disregard for it sure makes it seem that way. What they do love is Jesus, who this song is about. And Pokemon, which is the source of the song they adapt to praise God (see -- they must hate music if that's the best thing they could come up with to give Jesus mad props). They also seem fond of martial arts, if the sweet moves they show off intermittently in the video are any indication.
It's a little unsettling to hear a kid warbling about following Jesus's teachings every day one second, then seconds later pretending to murder another kid with a kick-ass neck breaker move straight out of some shitastic ninja movie -- but hey, maybe we just don't understand the Bible as well as these kids. Or something. Judge for yourself after you've seen the video.
