Excellent post Metatron.
It is hard to figure out why they do these things or how they get away with it. To me they seem to be schizophrenic. At times they seem to be teaching two different things at once. They have a long history of flip-flopping yet most witnesses just go along with what is in the latest Watchtower. Once in a while someone will freakout and run for the door but most witnesses are conditioned not to question anything they are taught.
