So what would you have, if you had the opportunity, told the families living and working in Jonestown? They had a doctrine and a close knit community too.
The difference with ex JWs is that we have hindsight. We understand that the JW doctrine easily kills off hundred's if not 1,000's of people every year. Jonestown was disgusting but it only happened once.
If it comes up I speak my mind. I try to be tactful not bombastic. I don't hunt down a JW and try to anti witness to them but if it comes up with family or if approached at my door I will ask uncomfortable questions about the two witness rule and the well documented RCA and the 1006 unreported instances of child abuse in and out of the congregation.
I will speak about the need for education and the foolishness of the blood doctrine and waiting on Armageddon. I will ask them why Jesus waited until he was 30 before getting baptized and why he never mentioned blood or Armageddon as the two prime central doctrines that the WTBTS promotes.
I would discuss the earlier years of the WT Society it's anti science stance, bigotry and racism. The great schism under Rutherford, the renaming themselves JW's when that is only a made up name for god. A name Jesus never bothered to revel. The current folly of the GB and there hunger for money by over charging for assemblies, there investment portfolio's, off sure banking and shaking down every congregation they have access to.
We have the knowledge and wisdom of hindsight..........we should on occasion..... use it.
P.S. The "let them bleed out" triggered another point. They used to practice committing suicide (Jonestown) in their after work meetings so on occasion they pretended and drank sweetened fruit juice miming the poison they would consume if ordered.
The JW's do it differently they walk around with a printed signed blood card/suicide note in their pockets.
