Yeah, he is and I have. Friends of his have described him as such before. He's a cross between Penn Gillette and Hitchens.

Moore is/was closer to Libertarian than anything when he wrote Watchmen. Over the years, he's strayed into the world of "progressivism" out of a reaction to Bush and Blair. And soon enough, he'll drift away from progressive and back to Libertarian because of Obama's nanny state. As great of a writer as he is, he has that George Carlin instinct of polar opposition to whatever is the mainstream.

Was Watchmen meant as a screed against Regan and Thatcher? Yes, but even Moore has admitted that the metaphor has changed post-9/11. And what Snyder has done to change the story actually works against a progressive, socialist message. Was Snyder aware of this? Probably not because because of the two years he's been developing this version could not have accounted for what's happened recently. But that speaks to the power of Moore's original work. The themes are universal and can be adapted to current history.
