I think this is the stage called grasping at straws. When all else fails, you look for something to cling to:
"Who cares about all the wrong/vaccilating teachings, wacky history, needless blood deaths, etc etc. All these apostates *must* mean it's the truth no matter what!!! PHEW!!!!"
It can also be:
-growth proves it
-everyone is so nice proves it
-uniform beliefs prove it
-a feeling I get in my heart proves it
-a random scripture says something that seems to match JWs perfectly, that proves it..
I had an old roomate who confronted me when I was leaving, so I told/showed him everything I had read. He almost left too, then did a complete 180.. His reasoning was simply "I don't care. I just know somehow it is the truth. <reactivate blinders>" (oh and by the way my parents will kill me if I leave the 'trufe')
Sorry Violet.. as everyone has pointed out, look at any group with similar characteristics to the JWs, you will find 'apostates' who make web pages, publish books, have discussion forums, you name it.
In fact if you ever get the chance, hang out with the active folks from one of the other groups. I had a Mormon friend once, and hung out with his family sometimes. They acted just like witnesses. Sometimes they would even talk about various teachings, they would act just like JWs, referring to publications and talks they had heard, etc. They never decided anything for themselves, they would always look answers up.
