The bots have gotten the idea into their heads that the movie is an attack on Bush (rather than an attack on totalitiarianism), and aren't about to be bothered with little things like facts.
If the Bush administration was like the British government in V for Vendetta, I would support freedom fighters trying to bring the government down.
But the Bush administration can only be compared to the V for Vendetta governemnt in the minds of fevered, irrational leftists.
