'The Story of the Jews'

Simon Schama wrote a series of books about the Jewish people. He began in 1000BCE and went through 1492CE in the first volume and continued it from 1492 until the present day in the second volume. A main reason he wrote these books was to be informative and historical documentation, but the books go deeper than the facts. Schama's whole purpose of writing this series was to capture the feeling of hatred, resentment, and discrimination that was put on the Jewish people. 
On Sunday morning, I am going to Poland for a week. I am going to visit concentration camps, ghettos, museums and Jewish towns of the Holocaust. Schama's books really relate to what I am going through this week because in preparation for Poland, we have been learning about the Holocaust and how it affected the Jewish people then and also how it affects us today. The Jewish people have been resented for thousands of years and I still don't really understand why.
Today in Jewish History we learned that Christians accused Jews of using the blood of Christian children in their Passover Matzos. This made me very confused as to why on earth anyone would ever think that. We read a couple articles about recent occurrences of modern people still having this mindset and accusing Jews of these terrible things. I think it was the governor of New York in 1928 that accused Jews of kidnapping and killing a girl for sacrifice. The illogical thing about it was that this occurred towards the end of the year, nowhere near Passover.
Jews have been criticized for being smart, successful, Jesus killers, and many more. No matter how many reasons people give me to try to explain why anyone would ever think such horrible things about people, I don't understand.
