Two things impressed me during this evening's (11/8/2013) Shabbat service. One was Holocaust survivor Kurt Roberg's presentation commemorating the 75th anniversary of Kristallnacht.
Another was Rabbi Schwartz's reference to a new Jewish Publication Society publication entitled Hatemail. The book presents picture postcards—yesterday's social media—which were widely used to promote anti-Semitism.
The link below will show you how today's social media are being used for the same purpose:
Three Poisonous Documents
You will see translations of three highly anti-Semitic documents found on Polish websites. I hope they will be used by some sociologists and students.
