Here's a scenario, say someone is df'd at 17 for sex. They leave and later get married with kids leading a normal life for a decade or so. He or she obviously hasn't been engaged in immorality for years so why should they have to wait a year to be reinstated if the chose to come back? ~Nowwhat?
That's a perfect example!
Years ago WT/GB instituted a program where elders were to contact DFd JWs once per year to encourage them to return. It was revised that those who once made it clear they had no interest could be removed from the visits, and those DFd who were known as apostates were not to be contacted. (Think that was to keep them from awakening the elders??) LIke most WT policies, that seemed to be forgotten or dropped eventually, likely because of so much negative response.
More recently they published the "Return To Jehovah" brochure. We had a couple elders who kindly dropped that off at our home. WT missed the opportunity at that time to make it obvious that the reinstatement of DFd who were not critical to the bOrg should have been encouraged to return as well as anyone only inactive. Yes, more would likely return if they were not humiliated to jump through all the hoops created by power hungry elders.
