THE FRIEDKIN/STONE SMACKDOWN: The Internet Movie Database says:

Oscar-winning movie-maker William Friedkin has hit out at Oliver Stone after Stone defended Palestinian suicide bombers. In a recent interview with Daily Variety magazine, Stone called Israeli settlers "vigilantes" and suggested a third party is sent into the area to restore peace. But his comments incensed Friedkin, who - according to gossip website Pagesix.Com - immediately fired off a letter to the Variety editor. The letter reads, "If Mr. Stone and I were in a land dispute, I would not be justified in murdering him or his friends and relations." And in response to Stone's third party idea, Friedkin snipes, "Will Mr. Stone volunteer his son or daughter to become part of this force?"
