No this isn't a troll post at all. I am a Christian who is a fan of metal. I got this shirt, of a band that is pretty in offensive and not an anti Christian band (none of their lyrics reference religion in general). And according to the lead singer, the name came from a BBC radio program he listened to as a kid. Dave Mustaine (who is a Christian, as I'm sure most of you guys know) is a fan of this band as well.
But basically my mum thinks this shirt is anti Christian. I didn't think twice about it since I got the shirt cheap and didn't find the album name offensive myself. I don't listen to blasphemous metal bands, don't even listen to Venom or Slayer.
