I am studying various religions in college and found the attached two expertises by ProfessorsLonnie Kliever of Southern Methodist University and Bryan Wilson from Oxford  extremely interesting.I have noticed that X members  (refered to as apostates) of a religion seem to create a lot of  sensationalism in the media and are often listed as reliable sources when in fact they are not and are often paid to say certain
things to stir up violence and hatred.
  For example I have noticed this  with former members of the Church of Scientology, the Catholic Church, Judaism, Christianity and other groups refered to as cults where incredible importance is put on the former Scientologist, the disaffected monk, the Jewish person who has turned to another faith and on and on.

Religious scholars have routinely found the testimony      and public statements of apostates to be unreliable.  In researching this area I found
a great book on the subject you might want to check out called
"The Politics of Religious Apostasy: The Role of
      Apostates in the Transformation of Religious Movement" by
      professor David Bromley, Department of Sociology and
      Anthropology of Virginia Commonwealth University.  He explains
      how individuals who elect to leave a chosen faith must then
      become critical of their religion in order to justify their
      departure.  This then opens the door to being recruited and
      used by organizations which seek to use their testimony as a
      weapon against a minority religion.. Bromley discusses the problems faced by Hare Krishna, The Family, Children of God
Scientology, Rosicrucianism and the Seventh Day Adventists.

I think you will find his site and the attached expertises  interesting
