I have not read
Arnon Groiss, author of the report, "Palestinian Textbooks: From Arafat to Abbas and Hamas", but I find it hard to believe a book like this would be baseless and bogus. He must provide some concrete examples. I'll have to look into it.

I AM skeptical about your post Emma that states "Time and again, independently of each other, researchers find no incitement to hatred in the Palestinian textbooks."
