Welcome IO
Keep reading and digging, but eventually your study 'teachers' will probably stop the study. They want to teach and persuade YOU, not the other way around. They always get wierd when someone fights back with legit questions, it stumps them because it wasn't something covered at the Theocratic Ministry School. That's where they are taught 'how' to preach so to speak and what to say, and how to turn around questions and answer them. It's quite robotic if you ask me. I was born and raised and when I use to go door to door and someone would ask a question beyond what I was 'prepared' to say at the door, I was stumped. I didn't know the answer, hence it provokes a 'return visit'. A return visit is a good thing to have on your time card when you send it in every month, it looks good on a JW!
The whole system is so backwards from what Jesus taught and meant. I wish you all the luck in your journey...
