"V (as in For Vendetta) hates Government so much he makes Glenn Beck look like FDR, but his enemies are thinly-veiled analogs for the Bush Administration. Which one's the liberal, again?"
Well, well, well, Bob. Apparently, you've only bothered to see the V for Vendetta film, which clearly pits V against a government that's a thinly veiled Bush administration allegory.
However, if you had even bothered to read the original comic series, you would note that Alan Moore (of Watchmen and League of Extraordinary Gentlemen fame - both originally graphic novels) paints V as an anarchist - a terrorist who wages brutal war against a fascist British government. V is no liberal avenger, as seen in the film version. He's a hero, a villain, and a psychotic madman - not unlike the Dark Knight's Joker. Nor are his enemies Bush-analogs. They're closer to some crossbreed between Mussolini and Stalin. Moore portrays a world spiraling into madness, a world devoured by insanity. V's fight is no liberal and just crusade. He fights heroically but madly, and is an agent of destruction and chaos, for the sake of murder and pillage against those just as evil.
V for Vendetta (film) certainly isn't a good case to illustrate political nebulosity. It's just a case of a Hollywood's liberals messing with excellent source material. Sure, V for Vendetta was an above-average graphic novel adaptation, and I enjoyed the film (went to see it twice, in fact). But you would be very wrong to use it as an example of political ambiguity without reading Moore's novel.
