I don't think that this particular poster is denying the holocaust or excusing it in the slightest.
What he seems to be referring to is the fact that Jews are normal human beings, just like anyone else in the world. They are a group of people united by a religious and ethnic background. Like all groups and individuals, they do great things and they do awful things. That God of the Old Testament that people make fun of so often around here? Yeah, they're the ones that made that guy up and followed him.
The point is that they are like everyone else, a mix of good and bad, and yet there is a tendency in the media to portray them as lovable saints who could not do anything wrong if they wanted to. This portrayal is to be expected - Jews are very active and successful in media industries and it is only natural for them to portray themselves in a positive light. This image is very strong and influential, however - look at your own reactions. Even a slight insinuation that individual people who happen to be Jewish can be vicious or dishonest automatically brings you to the knee-jerk reaction that it's antisemitism when, in fact, such individuals are common in ALL groups!
(EDIT: What follows here is NOT what I assert to be a history of actual events. It's a presentation of the historical perception of a group of people shattered by a major war. I didn't make this clear when I initially posted this comment and I apologize!)
The reasons that the Nazis targeted the Jews were a bit more involved than a simple, "They needed to blame someone so they could gain power." A lot of Germans believed that, prior to the entry of the United States at the end of WWI, they were winning and about to draw up a peace treaty that would have been in their favor. They believed that the entry of fresh troops on the side of France and Britain was what allowed for the shift of balance that ended in Germany's crushing defeat. They saw it all coming down to the Balfour Declaration. They saw the Balfour Declaration as an agreement between pro-Zionist Jews and the Brits. Basically, the Zionists would use their considerable media influence to bring the United States into the war on the side of Britain and France and, in return, Britain would give them the lands which constituted Palestine.
The war ended in crushing defeat for Germany with conditions of surrender that were, in hindsight, perhaps unconscionable. Germans basically saw themselves, as a people, in destitution. They saw Zionist Jews as the reason for their defeat. In addition, Jews were very prominent in their own country after the war - they were still prominent in banking, in the media, and in education. They were prominent in the socialist movements that a lot of Germans feared. The common German might very well have believed that the average Jew in their country had it better than them. Being human beings who have vices and failings like the rest of us, there were probably some Jews who DID take advantage of the situation and their positions to deal with Germans dishonestly and unfairly. This would have bred much resentment.
The Nazis, of course, played to these sentiments and pinned the actions of the expected few bad apples on the whole of the Jewish people. While in modern times we view Jews as just a religious group, such has not traditionally been the case - traditionally, Jews lived as outsiders with their own distinct ethnic and cultural heritages. A xenophobic movement like the Nazis would be expected to target the "aliens in their midst", even when there was no longer as much reality to that label. That this group which was considered to be composed of "outsiders" wielded as much influence as it did in the Weimar Republic made it all the more easy to target.
In light of all of that, I have to agree with the original post. Jews are human beings and not saints, despite prevailing media images. They were in a unique position to antagonize the German people when they were emotionally vulnerable and there were undoubtedly Jewish individuals who did so. The Jewish people as a whole most certainly did NOT deserve to be blamed for the circumstances of history or for the actions of a few bad characters in their midst. No group of people deserves what happened to them, no matter what it has done. It is silly, however, to act as though their people as a whole (EDIT: in its ABSOLUTE ENTIRETY) were a group of poor, innocent, and pure individuals who never did anything wrong and were targeted because Germans needed someone to blame for a loss in a war that arguably really was not Germany's fault in the first place - the events of history work in a more complicated fashion than that.
I apologize for the length of this post.
EDIT: I can see how I might have made it seem here that I am somehow justifying the Nazi response. I emphatically state that I do not and would NEVER do so. My point was that even groups that are full of wonderful people also contain bad individuals that can make the group in question look bad within certain contexts. It should not be "social heresy" to point this out.
