That was one particular male and one female. I don't see anything in your question to imply that it applies to anyone else, or to a lot of people. These people seem to have some kind of personal problem, but obviously no one should assault anyone when it's not necessary for defense, and especially a man to a woman.
But you said a "man" did it to a "girl", so maybe it had to do with parenting. Otherwise you should say a man and a woman, or a boy and a girl.
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.
