Torn - I too used to believe in 95% - I could not let go of the thought that even though imperfect, this was "God's true organization". It took a long time for me, and then a lot of soul searching.
Raised a JW, I never had even considered other possibilities. When I was thrown out into the world, I was scared to death!!! What I found in the world is much different then what I thought I'd find.
When I started to re-examine my beliefs, alone as no JW's would give me the time of day, I began to see something far different than what Jesus had said would be the signs of his true organization. One scripture, and I'm paraphrasing here as I don't have my bible with me, his apostles asked about ones coming with false prophecies in his name. His response - get away from me you - I never knew you.
If you still decide after doing all the actual research that the JW's are for you, then that is your personal choice. I've seen many JW's who post here who are not "belittled or condemned for their beliefs. Its the haughty, arrogant, judgemental ones that always get a good flogging - a much deserved one, as they are not God and do not have the right to judge the hearts of others.
