In talking to Moore – who is just as fascinating and voluble as you've heard – it becomes clear that the situation with his work at DC and in Hollywood causes him a lot of very real pain. As you can see from the transcript, you can disagree with some of his actions, but not with the real passion and love of comics that motivates them.
Since this interview was conducted, V FOR VENDETTA has indeed had Moore's name taken off the credits. The last I heard, his demand to have his name taken off the books he doesn't own still stood.
MOORE: "As far I'm concerned, the two poles of politics were not Left Wing or Right Wing. In fact they're just two ways of ordering an industrial society and we're fast moving beyond the industrial societies of the 19th and 20th centuries. It seemed to me the two more absolute extremes were anarchy and fascism. This was one of the things I objected to in the recent film, where it seems to be, from the script that I read, sort of recasting it as current American neo-conservatism vs. current American liberalism. There wasn't a mention of anarchy as far as I could see. The fascism had been completely defanged. I mean, I think that any references to racial purity had been excised, whereas actually, fascists are quite big on racial purity."
