Check out the "History on Trial" blog by Deborah E. Lipstadt, Dorot Professor of Modern Jewish and Holocaust Studies at Emory University.
I worry for my kids... about what they will do and what they will be taught / learn. I need to ensure that Olly and I give our kids the ability to reason and test the spirit of an idea/concept. I especially worry about people who deny the Holocaust and what their sickness could do to my girls. I admit I don't know enough on the subject but I do appreciate people like Deborah Lipstadt who do a great deal to shine a light on this dark subject and expose deniers like David Irving for the people they are. Check it out - its a worthy read. Also check out this article on the BBC News website: Link
