Jhine - Dont feel about not getting the original post, Cedars is well known in the EX JW world, but you couldn't have known that. He is still a Jehovahs Witness. I dont know his reasons, but many JWs stay in this reigion, because it teaches people to shun friends and family that leave, so they somewhat forced to stay. Some are working against the org from the inside.
Reaching Jehovah's Witnesses is very difficult. They usually attend hours of meetings every week to reinforce their beliefs. They are instructed to only read Watchtower literature and to fear and distrust any other source of information. The odd look you got when you tried to show them anything else is fear. You might try using just the bible, but the WTBTS twists the meaning of many scriptures, or use only parts of them, so they might get fearful even with that.
I have found asking questions is good. They are are comfortable answering questions, as they are taught to share their faith. if you ask the right questions, it may help make them think. If you google "cult mind control", you will see the JWs use every one of these methods. If you are really interested, check out Cult Mind Control by Steve Hassan
