A friend of mine is an Orthodox Jew and a professional. When she was in graduate school, she was assigned various anti-Jewish writings for a week. A few days into the ordeal, she found she had started to think of Jews as evil. She empathized more with the critics of Jews than with her own people. She started to look at the world through the prism of these enemies of the Jews. All it took was a few hours of reading.

Nothing in life is personal.
