Why does w.e.b. dubois refer to black soldiers as "soldiers of democracy"?

He believed that they were soldiers of democracy because they fought in a war to protect a world that disenfranchised them and segregated them and ended the reconstruction and what not. He believed that the country was being heavily racist towards African-Americans and yet the soldiers still put their values above this and fought to protect a democracy that didn't protect them.

A is the correct answer

You can easily rule out D because there are still conflicts to this day. Now you have it easier to get the right answer. WW2 was the first truly modern war, in the civil war and evem WW1 they still waited to see the whites of peoples eyes before they fired.  And the majority of the battles were actually fought in the north.
