Rebellious Spirit,
Welcome to the board, and I have really enjoyed reading this thread, your responses and the responses of others.
I can only speak from personal experience. Like you, I "think too much". The reason I left was because I was not allowed to "think". When I disagreed with a teaching (the blood issue, 144,000, why certain customs were forbidden like birthdays, but not others like piƱatas) I was not allowed to express that and get my questions really answered, but essentially told that I must simply follow the "faithful and discreet slave". I also didn't understand why we had to report time, why the flip flop on having householders pay for the magazines,and just a ton of other things. I didn't get disfellowshipped (mainly because I shut up quickly) but it was very clear that I was not "allowed" to believe things my own way, I had to believe their way. That drove me out, I faded away and haven't been back in over 10 years. My immediate family are staunch JW's, and initially they avoided me, but we are fine now. As long as we don't talk religion, and I allow them to make disparaging "jokes" about my being a pagan, everything is good.
There is the chance that you are lucky, and surrounded by liberal witnesses who don't try to police your every thought. Keep in mind, though, that with the change of a doctrine or CO, the atmosphere could change drastically. The society has changed direction many times in regards to non-believers and DAd and DFd ones. There was a time you were allowed to treat family members "normally", but those days are over. There could easily come a time when those who no longer study are to be treated in the same way. It would not suprise me (or countless others) in the least. And if a hard core CO comes along, he could counsel the body of elders on their "liberal" attitude, and they would follow that instruction blindly.
Good luck to you, and again, welcome.
Happyout - my name says it all
