I pretty much do not believe in god. This gives me a peace of mind concerning the false things I have been taught since I was a boy. I sometimes wish that I wasn't raised a witness but I know that I learned a number of great lessons as one.
I understand what your are saying and I have identified quite a few positive aspects of having grown up as a JW myself. Having said that, I also realize that even children who came from abusive homes or who lived during extremely difficult times in history, are able to glean fond memories and positive aspects of their childhoods. However fond memories, plentiful social contacts and positive experiences, do not mean a religion is teaching the truth.
I understand your feelings about the sometimes negative tone of some of the discussions here. I have felt this way at times but I remind myself that having grown up in the JW environment where people weren't free to express their true feelings about the world around them, may have left me a bit more sensitive than I need to be and it may have made myself and others former JW's here a bit unskilled at expressing ourselves in an appropriate manner, at times. For many of us here, this is the first time we have been part of a discussion group and we are in the process of learning how to share in an online discussion and how to sand the rough corners off the words that we'd otherwise get away with using in person because our tone of voice and facial expressions help convey our intent.
For me there is always something interesting to learn here but one does have to learn how to filter things out, learn not to take things personally and or skip over topics or posts that appear to be negative just for the sake of being negative. I also know that if one is on the lookout for offenses committed by others (very popular nowadays) they are sure to find them. That's why when navigating our way through the rough aspects of life, It's often better to put on a pair of slippers, rather than to try and carpet the whole world.
