First, you must understand that a Lion and Cheetah are different species. Humans are all the same species. It is like cows of one color or characteristics breeding with another cow of a different color or characteristics.
Same with dogs, cats, horses, etc. You were taught not to breed with people of a different race, and that teaching has stuck with you all your life. Learning racial segregation is not usually a class room setting, it is normally learned by observation of incidents or overhearing someone talking, or a variety of other subtle experiences you have had.
Humans are all the same species (as proved by Charles Darwin) so your question doesn't even make any sense. If you'd asked how a Homo sapien could be attracted to a Neanderthal that might make more sense. But we now know there was interbreeding between these two different humanoid species.
So, there's no accounting for the whims of attraction and as long as both parties are consenting adults it's really no one else's business.
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.
