Paris: Welcome to the forum. Are you an ex-JW? Some people on this forum have never been JW's and we welcome their sensible perspective. We hope to hear more from you.
lambsbottom: Take it easy. If you want to attend a Christian religious service and have never attended one, you might wish to start with the Methodist Church, as it may be the least offensive in terms of being middle-of-the-road. Personally, I love the Episcopal Church, but it might be a bit much for someone just exiting Watchtower indoctrination because it is ritualistic, much like the Roman Catholic service.
For now, keep reading and researching. If you have a college nearby and want to take some courses in Religion or related topics, that might also give you a good start. I took NewTestament and Old Testament survey courses, and courses entitled Introduction to the Study of Religion and Psychology of Religion. Your mind will open gradually and you will shrug off the brainwashing little by little as you go along.
Best wishes with your new life of freedom and free thinking!
