Again
in the entry on may 22, 1944, anne discusses the nature of prejudice and says that “what one christian does is his own responsibility, what one jew does is thrown back at all jews.” how does that saying explain prejudice? what other examples of prejudice can you think of?

This explains prejudice because it is having a misguided attitude towards something because of a bad example. In this case Anne is saying Jews get the bad end of the stick compared to christians, because when one Jew does something that isn't so good all Jews are placed in that same unfair box.

Other examples of prejudice is saying all black people are ghetto or rude, all white people dont like black and are racists, all rich people are materialistic. .

Ain the free market economic system the government is hands off from all supply and demand rates
