Lutz,
Without having any knowledge of your own circumstances all I can state is from your Post is that you are taking things too literally and with a certain degree of naivety. Parksy has explained a lot of the circumstances that led up to the assumption of power by the Nazis and I must admit that if I had been a starving German in the 20's and someone came along offering me a way out, I too probably would have been tempted. As Parksy has also explained, once in power Hitler changed the laws to ensure he could not be challenged, and if you so wish, to a certain degree similar things are currently happening to our freedom of speech and action all covered under the blanket of 'terrorism'. Whether we can stop it, or succumb is still a question. No, we have not yet reached the stage of blaming a race for all our problems but I do make the point that when the State issues laws that make it difficult for you to protest without affecting your freedom, then the majority tend to stay quiet.
The other factor which I feel is relevant is that Hitler was not German, but Austrian. Germany has accepted, almost too much the guilt of the previous generation, but in neighbouring Austria things are very different. There the events of the 30's and 40's have been buried under a blanket of silence where the State even still pays pensions to ex Concentration Camp guards living openly in Vienna. It may not be of much comfort to Germans but a number of the leading architects of the Holocaust were not German. Yes, there were bad ones, of that there is no doubt. But to blame a whole race for the faults of a few, is exactly the same premise under which Hitler operated. Again, I am not picking on Austria as a scapegoat, although there are many unanswered questions in connection with that country.
Even up to the 1940's there were many in the UK and certainly in the USA who thought that Hitler was a force to be supported. As we all know IBM was a supplier of computerised card data files to the Concentration Camps all through the War, and even the Kennedy's were very anti UK, and pro Germany when the late Joseph Kennedy was Ambassador in the UK.
So, there were many different events happening and so the guilt trip neither starts, nor stops with Germans. We should use history to guide us, not to control us and look forward positively.
