Searcher,
It would be very interesting to know this. And it would probably have to be anonymous due to the fact that the Society would organize a witch hunt for anyone having meetings not organized under their oversight.
Unfortunately, the anonymity of the poll itself would negate its results.
The AnointedJW site sometimes publishes anecdotal evidence of large numbers who do this. Exactly how large? -who knows - but I notice that the Society NEVER mentions such things happening - a sure sign that it is happening to some degree. They just don't want to give anyone who hasn't thought of it the idea.
Similarly, they sometimes speak of some partaking because of 'earthly problems,' past religious beliefs, and 'mental unbalance.' But they NEVER mention that some partake because of believing that all Christians should - even though they know that some are doing this. They just don't want to give the idea out to others who haven't figured this out for themselves.
