You can go much deaper. Voldemort is a "Half-Blood", his mother has married a Muggle. So he does not meat the expectations he has to his fellowers.
And Hitler, if you look at the pictures of the ideal german he wanted to create - you will not find anything of him in them.[/quote]

It is also interesting to note that some people think Hitler was part Jewish. I had a German History professor who said this isn't true though.

In any case, I agree that while Jo used history as an insperation, the Harry Potter books aren't supposed to be a retelling of WWII.
