So easy to say - but what the fuck does it mean? Do you mean all 'current' world leaders, or all leaders that ever existed, anywhere on Earth, down through the ages until the beginning of time?
So the Presidents that followed the American Revolution .. or French Revolution, were savages also? Compared to .. the rulers they removed? You can not wipe aside the necessity of past progress, you can not deny the absolute need for hierarchical organization at particular places and particular times .. if not for The Black Death & liberal democracy (acknowledging how badly it is failing us now), you'd be burning human shit for a living, like all your ancestors before you, under the boot of some fatassed Lord in FuckedInTheAssForeverShire.
Too much very easy to spew rhetoric where there is no coherent respect for all that has come before .. only then can a stateless future be pitched to the masses in a serious way, as just the next step in our societal evolution, not ... that mfer wants to create a program to give old people medicine for a lot less than they had to pay before ... HE'S EVIL AND SHOULD DIE! Just sound like spoiled children with no sense of history.
