Let's compile the 10 most most flawed teachings of Jehovah's Witnesses and provide sound reasoning and references as to why they are so flawed. This way we can all have this thread as a reference when it comes to disputing what Jehovah's Witnesses believe. We can make this a community project. I personally don't have all the reference material needed or even the knowledge in my head compiled to even get started on this but I'll give you several majorly flawed JW teachings to start with:
The Blood Issue
144,000 people go to heaven
List of false prophecies
Jehovah's name added to New Testament
Conflict of God's love and his justice (As in since there are 1 Witness to every 1,000 people in the world, for every 1 Witness saved 1,000 would die at Armageddon)
The Organization acting as God
That's all I can think of off the top of my head. Let's try to fill this in.
