Well, it depends on the Democrat/Republican you are talking about. Especially if it's a right-wing Democrat, it can be hard to distinguish the two. I'm going to link a website below (even though you didn't ask for it), but it tells you whether you're a Democrat or Republican by giving your views on some multiple choice questions.
It's extremely informative and gives insight on both parties.
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.
