A commentary on the reliability of "The Eternal Jew"" poster

Source1: A movie poster from the movie ' The eternal Jew'

Jews are the vermin of the human race and similarly spread disease and corruption. Unlike rats, however, the narrator continues, Jews have the uncanny ability to change their appearance and blend into their "human hosts." A scene depicts four bearded men in traditional religious Jewish clothing, then shows them shaved and in modern business suits, while the narrator explains that only a "trained eye" can distinguish their Jewish features.

Source 2: An excerp from Mein Kempf, written by Adolf Hitler
Since the Jew is not the attacked but the attacker, not only anyone who attacks passes as his enemy, but also anyone who resists him. But the means with which he seeks to break such reckless but upright souls is not honest warfare, but lies and slander.  Here he stops at nothing, and in his vileness he becomes so gigantic that no one need be surprised if among our people the personification of the devil as the symbol of all evil assumes the living shape of the Jew.

Source 3: Hitker's Willing Executioners, written by Daniel Jonah Goldhagen

The perpetrators of the anti-Jewish slaughter, Mr. Goldhagen contends, did not kill Jews because of threats or some German propensity for obeying authority. They participated in the slaughter because they were steeped in a historical culture of anti-Semitism. They tortured and massacred Jews, starved them, toyed with them, punished them for their birth, and they did so voluntarily, even eagerly, with unsurpassable malice and cruelty.




Source 1 is not reliable because the movie was made to show how terrible the Jews were and to show hatred to the Jews, so , they would obviously show only the bad side of the Jews.Also, by referring to Source 2 and Source 3, the sources said "they tortured and massacred Jews, starved them, toyed with them, punished them for their birth, and they did so voluntarily, even eagerly, with unsurpassable malice and cruelty" and "here he stops at nothing, and in his vileness he becomes so gigantic that no one need be surprised if among our people the personification of the devil as the symbol of all evil assumes the living shape of the Jew." Although the two sources was about showing hatred to the Jews and showing how bad they were,  the two sources were written by Adolf Hitler and Daniel Jonah Goldhagen, who both hated Jews, so they would also show just the bad side of the Jews. And because all of the sources were written to make the Jews look bad and had a bias tone, Source 1 is unreliable.
