Assange and WikiLeaks revealed the American military's war crimes, the American government's corruption and the American corporate media's pathetic servile flattery to the power elite. So, if you're a member of our ruling class, you would view those as textbook examples of dickery.
In a moment I'm going to list all the ways Julian Assange changed the world by being a dick.
In an evolved and fully realized society, the oligarchy would see Assange as a dangerous criminal (which they do), and the average working men and women would view him as justice personified (which they don't). We would celebrate him even as the mass media told us to hope for his downfall—like a Batman or a Robin Hood or an Ozzy Osbourne (the early years, not the cleaning-dog-turds-off-his-carpet years).
But we are not evolved and this is not Gotham City and average Americans don't root for the truth. Many Americans cheer for Assange's imprisonment. They believe the corporate plutocratic talking points and yearn for the days when we no longer have to hear about our country's crimes against humanity or our bankers' crimes against the economy.
