Prejudice

Prejudice is when people do not like another race or religon etc. for example, in the early and mid 20th century, the white abused african-americans because the white people did not like their skin colour. Another example is when the Jews were killed and humiliated during world of war two in Germany because Adolf Hitler did not like Jews and wanted to kill all of the Jews in his country.

What i want to learn more about prejudice is why people dislike another race or religon because the people who are abusing the others do not have a rational reason o dislike other races. For example, the white people who were abusing the black people did not have a rational reason to dislike the colour of their skin.
