Why aren't the Polish people viewed with discontent like the Nazi party in this pogrom?

First, it wasn't a pogrom--that's a specific sort of violence. Second, it was mostly Germans killing people. It was their infrastructure, their SS guards, etc. While there were non-Germans involved (more heavily not in Poland, incidentally), it wasn't their governmental apparatus doing it.

For sure, some Polish Christians had to have been involved in the deaths of their Jewish countrymen. Who in Poland allowed this to happen?

Could you explain what you mean? No one had to allow for someone to help the German government exactly.

Why did Hitler spend so much effort in eliminating Polish Jews and not German Jews?

Because of the placement of killing infrastructure where the Jews were in Poland, Polish Jews were close to ghettos and camps. Additionally, many German Jews emigrated pre-war after the rise of Nazism--that didn't occur in Poland to the same extent.

Some people do blame the Polish people. There was tremendous anti-semitism in Poland, and the Poles had been attacking and killing Jews in many numerous incidents in the late 19th and early 20th centuries, in events called Pogroms. On the other hand, the Poles were themselves an occupied, conquered country. They fought really valiantly and fiercely against the Nazis, but they lost. This means they were not in control of what happened in Poland. The Nazis were. The Nazis killed at least 1.9 million non-Jewish Poles. So you certainly cannot put the Pole's actions into the same category as the Nazi actions. There is however a lot of debate about to what extent some Polish people can rightfully be criticized for their actions vis a vis Jews during the holocaust. Poles will say not at all, and they get angry when people say, for example, that Auschwitz was a Polish concentration camp, because it was not. Auschwitz was a German concentration camp in Poland. It was not created or run by Poles. On the side of criticizing the Poles, however, you have events like the Kielce Pogrom of 1946. In this event, about 40 Jewish holocaust survivors were killed by their Polish neighbors. This was part of a wave of violence by non-Jewish Poles against Jewish Poles, and 1000-2000 Jews were killed in these various attacks. This led to a wave of Jewish emigration from Poland, so that very few Jews were left in Poland within a few years of the war. Others have criticized the Catholic leadership in Poland, because when they were asked specifically to condemn these attacks, some leaders refused, instead uttering words of support for the killers. At the same time it's important to remember that there were many Polish people who were hiding Jews. And there were many Polish people who were desperately trying to save themselves and their families and had no time to worry about others. So I am not going to make any comment about how much who is to blame. It's a complicated issue, and there has been a lot written about it, and there's no easy answer. To read a fictionalized account of Jews in Poland, check out Maus. It's the story of a Jewish couple in Poland, and what happened to them. The story is basically true, but it was written by their son, and it's a graphic novel in which Jews are drawn as mice, the Nazis as cats, and the Poles as pigs.

Hitler spent a lot of effort killing Jews wherever he could find them, whether Poland, Germany or elsewhere. It's not true that he spent more effort in Poland than in Germany. It's more like he showed less restraint in Poland than in Germany. The Holocaust began in Germany when Hitler came to power in 1933. But even if people didn't like Jews, it can be a controversial thing to announce one day that all the Jews are to be killed. So Hitler started relatively small in his efforts to get rid of the Jews. He started passing laws against Jews, designed to humiliate, isolate, impoverish and endanger Jews. It was a gradual but inexorable process of accustoming the public to think of Jews as subhuman monsters (read In the Garden of Beasts to learn more about this time in Germany--1933-1935). But because it started gradually, many German Jews had the means to escape. They had years in which to plan. For example, Anne Frank was born in Germany. When Hitler came to power, her family desperately tried to escape Germany. They couldn't get visas to go anywhere but the Netherlands, so that is where they went. They were still killed, but they were able to stay out of Nazi clutches until 1944. Other German Jews were able to escape more successfully, even though virtually no countries were willing to accept Jewish refugees (read about The Evian Conference if you want to learn more about that). Because of these factors, a higher percentage of German Jews survived the war. Plus, while the Nazis from early on showed no hesitation in killing Jews or being cruel to Jews, it wasn't immediately decided to commit genocide. There were a number of other ideas floated around, such as shipping all the Jews to Madagascar. Or sterilizing all the Jews with radiation, but not killing them outright, so they'd all be gone after that generation).

Another important factor to consider is that Hitler was especially brutal to those in Eastern Europe. The Nazi policies towards western Europeans were much less brutal, much less visibly murderous, as terrible as they were even so. When the Nazis invaded Poland, they killed fairly indiscriminately, seeing Slavs as lesser people. They started rounding up all of the Jews in Polish villages, marching them a short distance outside of town, where a mass grave awaited them, and then killing everybody. (Read The Holocaust by Bullets to learn more about these events.) This was witnessed by townspeople, and photographed by lots of people. When you have no restraints, it's easy to kill a lot of people pretty quickly. But in contrast, the Nazis were much less open about these things in Western Europe--France, Belgium, the Netherlands, and Denmark. They treated the people in general of these countries better, so they didn't have these rather public and open wholesale slaughterings. It's true that there were fewer Jews in Western Europe, but it's also true that the Nazis acted with a bit more public restraint, which meant a slower genocide. They'd still have killed all the Jews, it would have just taken longer.

Polish undergound organisations (like this one http://en.wikipedia.org/wiki/%C5%BBegota) tried to help jews as much as they could. But the problem is - Poles we're only in the SLIGHTLY better situation than jews during the war, it wasn't to easy to help such a big group of people without freakin army. And if German soldiers would noticed or even thought that you maybe helped a jew - u were dead. With all your family.

How can you really blame Poland for holocaust - it didn't participate in it. I won't say Poles generally loved jews, because they didn't, but they also never participated in mass killings of their jewish countrymens (in general, probably u could find some individuals, like in every other european country at that time).
