According to the "Vigiliant Christian" (aka Canadian conspiracy theorist Mario Emery-Paul Brisson), Slayers new video for "Repentless" is "Pure Satanic, Evil Filth"

""The fallen angels are in a battle right now against God and are working on this Earth to establish an antichrist kingdom, a New World Order, a Satanic, Luciferian kingdom. But to the average fan of death metal, 'Oh, this is just entertainment, man. You're taking it too far.' No, you are clueless and have no idea that there is a spiritual reality, and this stuff is, in fact, invoking demonic principalities in your life."

Awesome! Slayer should send him a thank you for the epic publicity :)
