The very concept of "race" was invented about 500 years ago (you can look it up online). So: the very concept of "race" was unknown to the Biblical authors, and none of the Biblical authors ever mention race, and certainly none ever condemn any particular race. Apparently they never imagined that such a thing as "race" existed.
Note that recent scientific studies have proved that there is no basis in fact for the concept of "race". That is: in fact there is no such thing as human races (or, alternately, there is only one human race).
No, it is not true that race doesn't matter in bible. The Bible talks of genocide against all non-Hebrews, and Jesus himself tells his disciples only to help fellow Hebrews and no others: These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not: But go rather to the lost sheep of the house of Israel. -- Matthew 10:5.
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.
