Does Angus know the ridiculous nature of the "singular/collective slave group" that only amounts to 7 men in a particular location on Earth? Is Angus familiar with the concept of a theological Captain Planet or Voltron?
Jackson uses group in a broad sense, like just anyone can be part of the slave group/class. As we all know, this is not the case and Jackson used deliberately deceptive language. Jackson believes the FDS is a collective made up of only 7 men who are in charge of doctrine and policy for 8 million JWs. Hopefully Angus does the research.
