I became an apostate through the door to door ministry!!!
I met once a hardcore atheist in the field service who took all my flawed Watchtower reasonsing so beautifully appart - with hard scientific facts - that I was left speechless - a born in JW of 36 years.
I was shocked back then but this key event started my awakening process by doing my own independent research...a year later I was out.
I wouldnt be surprised if the GB will replace the door2door ministry with something else soon as talking to normal people becomes too "dangerous" for the indoctrination of the cult victims.
