Pronounced Shith-e-ads, it refers to adherents of a philosophy called Shith, named for Shitheus, a 2nd or 3rd century Roman mid-level territorial imperial governor of a region in Gaulius. Corruption allegations did him in, accusations affirmed that he amassed vast land for himself, too much Gaul.
Any record of Shitheus and Shith philosophy survive today mostly courtesy of WikiLeaks and Wikipedia for their diligent digitalysis of historical research.
Among the basic precepts of Shith:
Always throw waste into the river. Or burn it up into the air and toss the ash in the river. Rivers flow to seas where the dumpwater disappears into the horizon where beyond there be dragons. Let the dragons deal with garbage.
Never make peace, especially with allies. Keep your friends close and your enemies closer to the extreme.
Always lie. Truth can be manipulated to conform to any point of view so why bother with logic and linguistics, just make up a story. Never mind if no one believes you, the more reason to keep lying because if no one believes you there’s no recognizing a standard baseline for truth.
Political opponents should always be rounded up and escorted to a sequestered place where they may consort among their own kind and be kept apart from disrupting the social order with contaminating ideas. Greek style athletic fields were ideal for places like this. And rock quarries.
Only one religion allowed but several deities were recognized by the state. Gods and goddesses were often submitted to the populace for popular vote, a Shithead scheme to foster a symbolic sense of republican democracy.
The poor of Shithead society were encouraged to eat their own children first before resorting to sell them as meat on the open market.
Slavery was common back then so it was assumed everyone not of the noble class could be enslaved at any time for any reason. Essentially all women, even noblewomen, were slaves.
The official line of the Roman empire of the day was that the borders were boundless, nowhere beyond the pale, but Shith philosophy foresaw the eventual takeover of Rome by the Barbars, and Shitheus a couple centuries ahead of his time identified christians as the number one threat to the internal stability of the empire. He himself predicted by a hundred or so years the eventual move of the imperial capital to Byzantium by Emperor Constantine, leaving Rome defenseless and in the custody of the pope and a few helvetic mercenaries. Shitheus preached a philosophy that attempted to militarize the up and coming christians to defend the empire against barbars, franks, turks, moors, anglos, saxons, mongols and you name it, whoever bordered the empire. Shitheus tried to get Jesus elected to the state sponsored pantheon of deities.
Abruptly at the height of power Shitheus was removed as territorial imperial governor and accused and convicted of high crimes and treason. He was sentenced to be beheaded and his history erased after his writings were intercepted and purged by order of the emperor’s tribunal that found him guilty. He escaped to a fringe hinterland. In an ancient twist of digitalysis, his philosophy persisted to influence leaders for almost two millennia even though his name and reputation were officially stricken from all historical records, and any references to him by name or inference were buried by dark ages historians and scholars as false (fake) history, called the Myth of Shitheus.
Even fake history repeats.
