Please show me an example of where a "Left/Arab" Israeli has published a book which uses religion to justify, or require, the killing of Jews. If you should manage to find such an example I would be very surprised if the people behind that book got off as easily as the people behind "the king's torah". Such a person would be labeled an "arch terrorist" and sent straight to prison, not questioned for an hour and then released. Frankly it is sickening that you think that these authors should be allowed to advocate for the people of one "race" to kill those of another, it shows how little some people learn from history.
