Revisionism is the re-examination of previously determined historical data to determine whether it is false and the attempt to change people's opinions of the facts. While this is possible with some areas of history, such as events that occurred before written history, there are some topics that should simply be left aside.

James Keegstra attempted to teach his students his revised version of the Holocaust in his school classes and encountered legal repercussions. The Keegstra case, which took place in 1990, was a court case held before the Supreme Court of Canada due to anti-Semitic statements and Holocaust denial within the school system.

He was also accused of attempting to foment hatred among his students against the Jewish people. James Keegstra was a well known and respected man in his town. He taught social studies, mathematics, and law to both middle and high school students (Bowal). He taught his version of what happened during the Holocaust in his social studies classes and taught how he believed Jews controlled the economy in his law classes (Bow). When news of Keegstra's teaching reached the school board, they immediately intervened, telling him that he must stop teaching his students his version of Jewish society and the Holocaust or there would be consequences (Bowal). Keegstra ignored the board's warning and his position as a teacher... half of the paper... has this ever happened to Jim Keegstra." Read Now. Np, July 1, 2012. Web.
