I think most of the jokehovian numbers are also bogus. Unlike the mor[m]ons, they do not have systemic doctoring of the numbers. They do it at the local levels. People turning in fake or pressured time slips. Hounders making fake slips in behalf of those who otherwise turn in nothing. Add this to the fact that many actually do time, but don't believe half of what they are told or do things against their own religion and are not accounted for, and you have inflated numbers. Not to mention those who turn in token service plus maybe one or two boasting session attendances per month.
I would like to see the numbers if they define "membership" my way. Only those who, according to their own theology, would definitely be saved if Armageddon would happen right now, count. Using this number, I would suspect well under a million--probably only 500,000 to 800,000 in this category. This leaves the majority being active but not sincere. Maybe doing token service, maybe practicing sin in secret, maybe wishing they were not in the religion in the first place. But, according to their own theology, such would be destroyed because joke-hova "sees hearts".
