Seconding Ber's answer --- NO.
What is this answering? I feel so dumb right now! LOL I can't follow the side conversations and just feel left out.
JW's are like everyone else. They have a wide variety of personalities. There are similarities---we can predict how they will react to some things---but they still do so according to their own style. I've known very mild, tactful, rude, fiery, timid, insecure, confidant, and reasonable JW's. I think it is wrong to just pigeonhole them all, and then go on the premise that they are all the same--and then patrol a forum looking for traits you identify as JW. Afterall, it is not the opinion you are objecting to, it is the expression of that opinion. You don't like how I express my opinion, and think that you are in a position to judge such and tell others how they should present their thoughts. JW's may be presenting the exact same thoughts, but they all have a unique style.
