I have read what he wrote about the changed scriptures. It is obviously wrong, because everybody can see the archeologic finds in the Judean desert. Lots of them are digitilized. So even without visiting the Shrine of the Book in Jerusalem everybody can see, that nothing is changed.
He ignores the fact because of his ideology. I thought the leftists are so in favour of scientific prooves. I guess only if they are prooving their false theories.
