No body knows why sexuality exists. When you say go gay your pointing to gays making a choice to be gay. Its not by choice.
The logic expressed makes as much sense as say suggesting a blind person chooses to be blind despite there being so many wonderful things to see.
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.
