Wow what a neat question. I have totally changed my answer like 20 times but all in all I would say 3, and I have a feeling the numbers will be on the lower end because of what most of us were taught an apostate is.
I have obsolute no ill will towards any witness. There are many who feel this is the truth and have found their peace and I am truly happy for them.
I believe that JW's as a whole truly do care about God and what he thinks and try to be good people.
I believe some of their man made rules make them no different then the organizations during Jesus's time that he was told he would bring down.
The way they shut off the world is not loving. We were taught not to associate with these people but yet Jesus went straight to them, ate with them etc, I see great contridictions.
I thank the Witnesses for giving me a new perspective on God and this world etc. I am always open to anthing that makes me think.
All in all I never really let them control my life (bad Witness, bad Witness) as much as others so my attachment is not as strong, so it is a clean easy escape for me so far.
Thanks for posting this question, I can not wait to read the replies.
