the OP`s reasons?
The basis for motive is everything and communist propagandists rely on censoring any questioning or criticism of their message.
Communist propagandists always fear and resent having to explain themselves. Just like you are attempting to do here.
You may genuinely believe that Poles need to be passive, deferential and apologetic to Germans but your own familial reasons for doing so are invalid.
Poles owe Germans nothing and most certainly should never be seeking their approval like a German bastard child would with its Mutter. :)
