Hi Conan ,
Firstly : Welcome to the board , your brain seems to be functioning alright by me , you are reasoning quite well on what has been presented in the previous posts.
Secondly : Whatever you do don`t get baptized ,it will ruin your life.
Thirdly :It`s true their are many genuinely nice / good people who are J.W.`s , but that fact doesn`t mean they have the " truth" anymore than a Baptist person who is a good caring loving person has the "truth" or a Catholic person who is a good loving caring person has the "truth" or even a Muslim who is a good loving caring person , does not mean they have the "TRUTH" about religion.
If you decide not to continue your studies with your "friend" and he decides you are no longer his friend , then he is the loser not you , he was not worthy of your friendship , if that is the case.
Take care mate ,from Australia.
