"Notice the sleight of hand… Each of these assertions is a blatant falsehood. But these historians, having, through their control of institutions, set the standards of intellectual correctness, the one who questions the falsehoods, even though he does so by citing the writings of the best known Islamic historians of those very times, he is the one who is in the wrong… Once they had occupied academic bodies, once they had captured universities and thereby determined what will be taught, which books will be prescribed, what questions would be asked, what answers will be acceptable, these historians came to decide what history had actually been!… Thus, they suppress facts, they concoct others, they suppress what an author has said on one matter even as they insist that what he has said on another be taken as gospel truth. And when anyone attempts to point out what had in fact happened, they rise in chorus: a conspiracy to rewrite history, they shout, a plot to distort history, they scream. But they are the ones who have been distorting it in the first place – by suppressing the truth, by planting falsehoods."
