Sorry I don't buy it. Whatever was researched could be hidden and covered up. Of course proof can be destroyed and hidden so what went on in court doesn't convince me. No amount of research etc can convince me. Do you also agree with pharmaceutical research?
If you were an eyewitness to the atrocities then I'd listen. You and I are lucky enough that we didn't have to experience WWII. We can sit in the comfort of our homes and express our opinions but truly neither of us knows anything about the reality of it.
That's why I trust far more someone who lived through those times and knew someone who was in the camps. (And this poster isn't a newbie but a very longtime and well known poster on CZ)
This poster said nothing against the German people. It's not about that. Their leadership wasn't their fault.
