Adolf Hitler, Our Contemporary by Srdja Trifkovic

Given the reaction against the graphic violence in the Temple of Doom (the tearing of the heart out of the sacrificial victim) that lead to the creation of the PG-13 rating, was that any worse than Nazis melting and blowing up in Raiders of the Lost Ark? Was someone or a group exercising undue influence on the MPAA to let Raiders of the Lost Ark slide with a PG rating because the depiction of such violence and gore was acceptable since Nazis were the ones dying in such a grotesque manner? After all, it was some sort of divine justice being portrayed through the opening of the Ark of the Covenant, with God's enemies being smitten by the angel of death?
