Without getting too caught up in the politics involved, I would guess that Schiff may have been unaware of any negative ramifications regarding the UNESCO ads featuring Superman.  I won't question his sincerity regarding them.  If I could use a more present day analogy, a lot of people, myself included, who would give to the United Way were unaware just how much the organization was paying it's top level executives which was a considerable amount for a non-profit organization.  When the salaries became known the ensuing backlash that it created forced the United Way to rethink it's philosophy.  I would give Jack a pass.
