Hi Rory,
Your idea sounds good, but it won't work on a one-by-one basis. You'd need every closet doubter (and there's lots of them) to act at the same time. Here's what might work: get the word out to every 'apostate' site on the web so every closet apostate knows when to act, then call for a general strike (no meeting attendance, no field service, nothing JW related), now set the date (I'd suggest Dec. 21, 2012 - the end of the world :)). Now everybody go on strike and stay on strike till the WT caves. I suspect that such a bold, unified act would get the flcoks attention too, lots more would ask questions and switch sides to the apostates. Be interesting to see it happen and do a head count. I suspect there's not many who actually drink the kool-aid of WT propaganda, most stay out of fear, as you said.
