DISTURBED's Belgian Show Cancelled Over DAVID DRAIMAN's Photo Signing IDF Missiles
(metalinjection.net)
Dude has always been an edgelord in some capacity. He probably thought it would be edgey to sign a bomb, regardless of who made it and who it would kill.
Though, I have zero doubts that David also has some questionable viewpoints on that stuff as well. I'm not aware of any, but I also haven't really heard anything from that band since the late 90s/early 2000s.
Good job getting cancelled buddy. Enjoy obscurity.
