"These are people who believe in entitlement. These are arrogant elites who believe the rest of us don't need to know what they're doing with and to our lives. These are people see truth as a danger." David Michael Green, "What WikiLeaks Really Reveals" Common Dreams, 12/5/10 (http://www.commondreams.org/view/2010/12/05#comment-1686473)
The key word here is not "truth", which they do indeed hate but which is incidental to their main purpose, but "entitlement." The political elites and their ideological attack dogs reserve special savagery for whatever threatens to unravel their self justification. In the words of Derrick Jensen, "It all comes down to perceived entitlement. As Bancroft states, 'Entitlement is the abuser's belief that he has a special status that provides him with exclusive rights and privileges that do not apply to his partner. The attitudes that drive abuse can largely be summarized by this one word." The abuser has the right to lie and we must accept his lies and pretend that they are the whole truth and nothing but the truth. Doing this preserves the abusive family dynamic.
Again, Jensen, "Within an abusive family dynamic, everything - and I mean everything - is aimed toward protecting the abuser from the physical and emotional consequences of his actions. All members are enculturated to identify more closely with the family structure and its abusive dynamics than with their own well-being and the well-being of their loved ones and other victims...This 'well-being' is a particular sort, devoid of relationship and accompanying emotions, heavy on the kind of external rewards abusers reap because of their abuse (and of course precisely the kind of external rewards emphasized by a grotesquely materialistic culture), and most especially focused on allowing the perpetrator to avoid confronting his own painful emotions, including the pain he inflicts..." Derrick Jensen, Resistance, p. 564.
What the abuser fears above all is the sight of what he has done without his preferred moral justifications - justifications that allow him to carry out acts such as the murder of a million Iraqis, nightly drone attacks that kill far more women and children that supposed "terrorists", and gutting climate change to doom future generations to thirst and starvation.
DMG is right that they have little to fear from a pacified population, stultified with cheap goods, overwork, and hypnotizing spectacles. Jensen: "People will do anything - go to any absurd length - to hide the abuse from themselves and everyone around them." What Assange has done is expose the global abuser and his family members have rushed to protect his feelings.
