I enjoyed this story and I'm glad his work was ruined. Perhaps Banksy will realize he's wasting his art on barbarians and their barbaric causes to ethnically Jews from their indigenous homeland. From Palestinians Vandalize Mural by British Artist:
Bethlehem residents have painted over a satirical mural by the graffiti artist Banksy that was meant to highlight their plight. The British artist had painted six images around the town to help drum up tourism before Christmas.
But the irony behind the depiction of an Israeli soldier checking a donkey's identity papers was lost on some residents, who found it offensive.
