Just writing down some notes to share with JWs when I meet them. Here are a few of the problems of logic I see in their doctrines. Perhaps you can add to them.
systemic contradictions – jws boast about fighting for religious freedom – that is their freedom to share their differing views with people outside the organization - yet there is no freedom amongst members to disagree with any official teaching within the organization without the threat of losing friends and family
illogical blood policies – While plasma is banned, all of it's ingredients are on the acceptable list; white blood cells are banned yet millions passed through mother's breast milk to her JW baby. Twelve times the number of white blood cells exist in organs than in the blood stream, yet WTS allows organ transplants
Jws say that there were less than 150,000 faithful Christians that ever existed prior to the 20th century. Yet there were allegedly 7 million Christians who were martyred in the first 3 centuries of the common era alone. It doesn't make sense.
4.The WT organization associates the UN with the beast of Revelation, yet joined the UN for ten years as an NGO as they say to get a library card.
5. Jws believe it is wrong to take oaths of allegiance in support of their country and its political values yet their leaders do sign oaths of allegiance to get their passports.
