I'm sometimes shocked and appalled at how anti-semitism still runs rampant in the Orthodox Church (and Roman Catholic Church, and just Europe in general) under the guise of "anti-Israel." One can be against Israel's policies without being against the Jews, downgrading the Holocaust, or demonizing an entire people group.
For one, Communism is and always will be a Christian heresy. It is not a Jewish construct by any stretch. Though Karl Marx was ethnically Jewish, he was an atheist as well as a strict materialist. He took the Christian social Gospel and removed God from the equation and instead instituted the collective, which is why it is a Christian heresy. The reason Communism is treated with these so-called "kid gloves" isn't because it's a "Jewish construct," but because most academics actually believe it's a good idea. I've had friends go so far as to say that a violent revolution is needed, along with the killing of political dissinters. That has nothing to do with Communism being Jewish, but everything to do with it being materialistic. Even neo-Marxism and post-Marxism have become softer on religious views, seeing religion not necessarily as an opiate, but something that can be used to transform the world into a collective.
As for Germans not knowing what was going on, the reality is they did
. The Americans knew they were committing genocide against the Native Americans, but justified it under "Manifest Destiny." The Spaniards knew they were enslaving the Native populations in the New World, but justified it as prosperity. The English knew they were killing and murdering Africans, but they justified it as necessary. The Turks knew they were murdering Armenians, but the people justified it as in the nation's best interests. Likewise, the Germans knew that Jews were being used as slaves and even being killed, but they justified it as a cleansing. With some 42,500 Nazi camps throughout Europe, all meant for undesirables, there's no way the average German could plead ignorance to what the Nazis were doing.
Third, having German blood does not justify a defense of Germany. You have German blood, so what? Your genetic ancestry is quite irrelevant to the truth of the matter. If we all traced our genetic ancestry we would find that we descend from murderers, rapists, and genocidal maniacs. That is simply how the human race works. Our job isn't to defend our history and put a rose on it, but to correct the past mistakes and create a better future.
We live in a fallen world. Buying into nationalism or racism doesn't fix our problems. Trying to justify an evil act - such as the Holocaust - doesn't make things better. Yes, more focus is placed on Jews lost in the Holocaust, but that is because they made up nearly 50% of the victims. Regardless, all lives lost in this tragic event should not be downplayed or seen as a cause of their own demise. That is not the Christian approach to this matter. Rather, the Christian approach is to realize that we are all fallen away from God, that we are all murderers in our own way, and that we should seek to correct this error through Grace. Anything short will result in failure.
