Why did african american and other minority men find postwar discrimination especially upsetting?

In the postwar period, the situation was not changed dramatically when it came to racial discrimination int he United States. There were still many people that didn't wanted to have anything with the people of other racial groups, and did not saw them as equal to them. This was very upsetting for the people of other racial groups, such as the African Americans, Native Americans, the people of Asian ancestry, especially because they risked their lives for the country and for the people living in it during the war. They could not understand who is it possible that they put their lives on the front in order to protect the others, just to be discriminated again when they came back home by those same people that they were fighting for.

where is the passage?

can't without the passage.

post the full question.

i believe the answer is:

-   william jennings bryan is a democrat while mckinley was a republican

at that time, the segment of population that choose for democratic party were the voters with low economic background and vice versa

- william jennings has support of populists and wants to have inflation to farmers while mckinley has support of bankers and businessmen , doesn't want inflation

the fixed value of gold make the large business able to stack up their gold without   being worried that it would devaluated.

- william jennings supported the silver standard while mckinley supported the gold standard

according to jenning, using other metal beside gold could the poor people to have more purchasing power and them advance in the society.
