That's a comment I heard on the Mothercorp yesterday.
It was in a piece about China's treatment of NGOs. The Chinese government is suspicious of NGOs, especially in the wake of Ukraine's Orange Revolution and also the (presumed) tendency of American NGOs to proselytize (for whatever their agendas might be -- democratic, social, political).
I quote this phrase because for me it's an indication of how twisted we can get in our thinking merely through the use of words.
Think about what this phrase is saying: Dangerous agents of peaceful change.
It just goes to show that Bush et al have no monopoly on the creation of Doublespeak.
