The idea that knowledge (or civilisation) can be "stolen" from others, in the way that artifacts (eg, books) can be stolen, and that such "stolen knowledge" is forever lost to the originators of that knowledge (or civilisation) is so patently looney it really does not deserve discussion. The only possible way this could have been achieved would have been for the Greeks (or other evil whites) to have utterly exterminated the inferentially superior (sic) black (sic) creators (sic) of such a civilisation (sic). And, to the white mans everlasting cost and grief, this ultimate world-cleansing ecological achieveMUNT was sadly was never even considered by white men - not even by the Boers - although they had every incentive and right to do so after one third of their number were treacherously and butchered by the cowardly Dingaan, Shaka's half-brother and assassin.
(Shaka, btw, despite his bloodlust, clearly admired the whites. It is rumoured he learnt his devastating military tactics from his mentor Dingishwayo who, whilst an outcast from his tribe, had spent a lot of time with a British officer who had deserted and "gone native". It is more than likely that, over camp fires, the renegade oficer spoke about military tactics and transferred some of his knowledge to the carefully-listening black man. Anyway, as he was being budgeoned to death by Dingaan and accomplices, Shaka reputedly said "you fools, the white men will now come and conquer you".)
Something never remarked upon is that, historically, genocide is rarely if ever performed by a superior race. On the contrary, it is ALWAYS performed by a cognitively inferior (but numerically superior) race/group against a cognitively superior (but numerically inferior) one. The Nazi's did not contradict this generalisation because, although the Germans are quite probably the most intelligent European nation, Ashkenazi Jews are even brighter. This was an extremely rare, possibly unique in all of history, example of an otherwise highly civilised people engaging in genocide.
The tragic upshot of this episode is that, post WW2, the best interests of the white race have been irreparably harmed by legions of guilt-wracked "white liberals" subjecting the entire white race to everlasting penance and humiliation in the form of "multi-culti" race mixing - a course which can only lead to our own self-destruction - in a foolishly misguided attempt to right this historic wrong...! The post WW2 policy of giving "freedom" to inferior races which have been "oppressed" by whites is part and parcel of this penance seemingly without end. Indeed it would be no exagerration to liken it to a gigantic sacrificial offering - a free feast for the "useless turd extruders" (UTE's) of the "turd world" - in which Rhodesia was the small but tasty appetiser, South Africa the substantial and delicious entre, and no prizes for guessing the name of the yet to be served but enormously rich and satisfying main course...!
In case any of the jewish and american liberals who generously "donated" Rhodesia and South Africa to the "UTE's" are reading this - dont say you weren't warned..!!!
The greatest irony of all is that, ultimately, the white race (of which Ashkenazi Jews are a part) will suffer far more from this never-ending penance than the original victims.
To continue where I left off -
Assume I am the inventor and world authority on hydrolastic dododecahedron widgits (HDW´s). Nobody can "steal" my knowledge from me although, through books, articles, lectures, and the electronic media, I can if I wish choose to disseminate my encyclopaedic knowledge of HDW´s to the ignorant unwashed masses. But, unless my knowledge and expertise is absorbed and taken to new higher levels by another (smarter and more capable) individual, I will remain the world authority until I die or am otherwise eliminated from society.
Note that the person/persons who manage to climb new heights of HDW´s must either be cleverer or more vigorous (or both) than myself. Thousands of years of total lack of achieveMUNT have shown that this is clearly NOT the case with blacks vis a vis whites.
The very fact that many blacks have convinced themselves that "their once great knowledge" was irretrievably stolen from them by evil exploitative whites, is in itself compelling evidence that they are the complete imbecilic morons they most assuredly are...!!!
