There is no evidence you've suggested to call someone a rapist. Plenty of evidence to call you an ill-informed idiot though. As the charge of "rapist" can only be brought after a court of law has looked over the evidence.
You cannot judge the past by today's standards and laws. Neither can you base your entire premise on one solitary interpretation of an historical event.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
