During the last forty years or so, revisionism has become a fighting term. To so-called revisionists, it implies an honest search for historical truth and the discrediting of misleading myths that are a barrier to peace and goodwill among nations. In the minds of anti-revisionists, the term savors of malice, vindictiveness, and an unholy desire to smear the saviors of mankind.
