I seem to remember that before 1980/81 people who dissociated were not treated like disfellowshipped ones??
Then there was an announcement around 1980/81 that we were to treat disfellowshipped and disassociated ones both the same...
The pre 1980/81 years seem like much simpler times if you wanted to leave the watchtower voluntarily without recrimination and shunning...
