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

Source 1:

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 excerpt 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: Hitler'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.

Commentary on how reliable the image of the Jew has been depicted in the poster.

I disagree to a certain extend that the image of the Jew that has been depicted in the poster being reliable. From source 1, i could infer that the author was bias against the jewish as he said "Jews are the vermin of the human race and similarly spread disease and corruption". They could meant that the author dislike Jewish and assume them to be as good as vermin. Not only that, the author also commented that Jews have the ability to change their appearance and blend into their "human hosts". This could mean that the author had an impression that Jewish are as if plastic dolls. 

However, this source could not be reliable as both sources were one sided and not supported by both pros and cons. The author of the three sources might be bias or forced to only publish the negative side of the Jews and not publishing the whole story behind the scene.
