>>What Mark objects to is when Beck reads from Mark’s book and doesn’t give any attribution.<<
From what I can see, no one has been able to give an example of “reading” from Mark’s book.
If it’s just that Beck has quoted from Mark’s sources i.e. gave the same info on Cass Sunstein that Mark did, it’s not really from the book.
If, however, Beck lifted the commentary Mark gave regarding that info, that is stealing and not right.
Mark has cited the instances on his show. Sorry I do not document them or have the shows recorded.
