Movie-maker Oliver Stone has blasted media groups who "slander" celebrities for their political comments - because intelligent stars have every right to question their leaders. The Vietnam veteran, who is a fierce opponent of the US leadership, is appalled every time a celebrity is rudely mocked for making his or her thoughts about PRESIDENT George W Bush and the war in Iraq public, and he urges journalists to be more supportive. The Natural Born Killers director says, "We're Hollywood wackos and all that stuff, left-wing... (It's) an easy and facile dismissal. "I'm still a citizen, I've served my country as a veteran, I've had many jobs before the film business. I know something of life, having lived to this age. "We have a right to speak and every time we speak: 'You're an actor, a showbusiness director,' we're making it up! "This is not a way of dealing with people. This is slander."
