Much of what is "known" about the Holocaust is the product of the Zionist propaganda campaign that can realistically be reckoned at over a hundred years old - both as to who "knows" it, and what they "know."
The advent of the World Wide Web has radically altered the venues of information and its transmission, with Wikipedia forming a conspicuous and influential locus within those venues. In today's e-mail, Gilad Atzmon passes on an article in Britain's Guardian newspaper describing the recruitment and deployment of information guerrillas specifically trained to operate in the jungles of Wikipedia, the free, online, user-edited encyclopedia to which practically everyone who uses the Internet has occasion to refer at one time or another.
Here, as everywhere, beware Zionist saboteurs - they are well trained, well funded, and numerous, despite the deceptive (and plaintive) whining in the article about how badly they are outnumbered by their opponents. As an experienced Wikipedian in my own right, I can testify from brutal personal experience as to the pile-on that instantly occurs just as soon as anyone sets about correcting any distortion favoring Israel or the account of the Holocaust that sustains its depredations on the world.
