While I was still in, I heard of some exjws who had become "apostate". I would never have talked to them or listened to anything they said. My guard would have been up.
My waking up had to do more with questions that a non-jw at work started to ask and I found myself struggling to make our beliefs sound logical.
I think there are different things that awaken each of us. With some, it's seeing things crumble from the inside. With others it's exposure to nice non-jws. For some, they looked up stuff online and I really doubt someone sitting you down and trying to "reason" with them about JWs is going to help them wake up. You have to already kind of be going down that road and open to doubting the "truth". I don't really try even bringing up JW stuff when I'm with the family...but, I make myself approachable (non-confrontational/loving) and lead a happy life so that if ever someone wants to come up and ask me questions..or a place to stay or whatever- they know I'll be there for them. I don't want to be that crazy exjw that they'll automatically dismiss because I'm always trying to prove them wrong.
