It's happening again.
Michael Moore has a new movie, Capitalism: A Love Story, and the mouthbreathers are in full Greek chorus mode before they even see it (read the comments in response to the above linked story).
As I understand it, Michael Moore is a hypocrite because he's rich and he criticizes the supply side economics the U.S. has practiced for the last three decades. If Moore were heavily invested in the stock market and criticized it in his film, that would be hypocrisy; however, he isn't heavily invested in the stock market (or so he says). He's made his money in filmmaking, rather than investing.
There is also the point that FDR was more wealthy than Moore and much more critical of the wealthy exploiting the poor. Rich people can have shame about their peers' exploitation of the poor, and poor people can rabidly defend rich peoples' rights to exploit. I don't know why seniors on fixed incomes and working poor people rally around the half-assed economic theories of clowns like Limbaugh and Beck, but I don't think they are hypocrites for doing so.
Moore is candid at all times about his politics, and he uses his films to advance those politics. You know that going in, just as you pretty much know what you're going to hear when you tune into the aforementioned Limbaugh and Beck.
This is yet another example of a trend I'm noticing more and more at the day job: anti-Obama/anti-Democratic reactionaries who cannot bear even the existence of conflicting ideas. I run one letter to the editor defending Obama and a reactionary will scream bloody murder about liberal bias. I run a letter to the editor opposing Obama and I might get one response from a liberal objecting, with much more civility, to an assertion made against the President.
I don't really despair over this; it's mostly a symptom of slow, but steady, decline of the George Wallace/Richard Nixon/Ronald Reagan voting bloc. Our political culture is comprised of pluralities and this one is dying out, in part due to age but primarily because working class whites are slowly coming around to the realization that they have been fucked hard by corporate flunkies posing as Reagan's heirs. The smaller the group gets, the more shrill the diehards are going to be.
