I feel I've really toned my need to judge people all the time. Though, to be honest, the inclination still persits. Introspection isn't a one time thing. It's a continuall evaluation of where you stand and why you're behaving the way you're behaving. But by being cognisant of my backround I do find it much easier to accept people for who they are now - instead of just stressing over who I want them to be all the time.
As far as being a "know it all" - well, I can't really say that's really changed too much. But I am much more comfortable with saying the words, "I don't know." And when I find out I'm wrong about something I can now pallet the saying, "Hey you know what, you're right about that." (It's amazing the amount of respect you get when you can admitt you're wrong). More importantly, I have done a tremendous amount of research since I learned the TTATT. And the more I learn, the more I realize just how little I know.
The real problem with being a JW isn't how little you know about everything like the Bible. It's that you think you know everything about the Bible. But when you're a witness you don't know who wrote it, when it was written, how it was compiled, how many versions exist of it, old books that used to be in it, new books that were added later, the metrics to use to tell historical accounts from litterary devices, etc. The JWs just do kindergarten theology. They think they can read a 10 page creationist brochure and become an expert on biology. Or read one of Paul's letters and become an expert on psychology. Or cherry pick Bible versus and become an expert on ethics. The WTBTS discourages higher education, philosophy, research, and evidence based reason. It's no wonder I was so judgmental and opionated - I didn't know what it meant to be rational.
