The vocalist of US death metal group Cattle Decapitation has hit back at a fundamentalist Christian group after they used his band’s artwork without permission in a recent Facebook post.

Over the last two decades, Cattle Decapitation have made a name for themselves crafting some of the most brutal music you’ve most likely never heard. While their extreme nature doesn’t just stop at their music, with their videos and album artwork also featuring rather confronting imagery as well, it’s not very often that you’d expect a Christian group to feature the band’s artwork on their social media accounts.

As Metal Injection reports, a fundamentalist Christian group named ‘True Bible Christians” took to Facebook earlier this month to share a seemingly-typical meme to their page.

The meme in question was accompanied by a Bible verse and featured anti-evolution rhetoric alongside an image of a human-like creature eating meat. However, the image in question just so happened to have been ripped straight from the front cover of Cattle Decapitation’s 2012 album, Monolith Of Inhumanity

Taking issue with the group’s unauthorised usage of the image, Cattle Decapitation vocalist Travis Ryan took to the comments section of the now-deleted post to serve up a no-holds-barred response.

“I’m the one who commissioned that art piece you stole for your dissemination of your little fairy tale,” wrote Travis Ryan. “Its by the artist Wes Benscoter.”

“It seems, per usual, you people cannot follow your own bible. Remember ‘THOU SHALL NOT STEAL?’ You can’t even get that one right.”

“You are garbage. Your religion is on the top of the garbage heap of organized world religions similar to that monolith there which represents the ills of humanity,” he continued. “That’s you. That’s your man-made nonsense. You are thieves. You are garbage. You will always be garbage. Remember that.”

While the post has since been deleted (presumably with no apology to Cattle Decapitation, Travis Ryan, or artist Wes Benscoter), plenty of fans have applauded the vocalist’s decision to stand up to the group in regards to their divisive posts and methodology.

Whatever the case, we have a pretty strong feeling that Cattle Decapitation won’t be invited to the next True Bible Christians fundraiser.
