For example in my (european) country all people have had witnesses at their doorstep but almost none ever saw a mormon show up.-ISTKH
So ISTKH you live next to a LDS ward yet you claim that no one ever sees them come to their door? What the hell is the ward for then? Members that come from out of the country or imaginary members? But certainly not members who were preached to or converted in your neighborhood!
I wonder how many of the JW in the 8 million are of the 15 minute category like my Alzheimer's stricken mother or my bed ridden aunt who some how magically put in 15 min? Do you have numbers for that?
Also, my drunk atheist uncle attends the memorial to appease my aunt so maybe thats why they dont count memorial attendees. Also many of the attendees are mentally unstable annointed ones so maybe we shouldnt count those as witnesses. Also, the number of witnesses counts those that are later disfellowshipped that same year. So I wonder how many of those we can subtract.
So, if I can pull a number out of my butt I would say that maybe 4 million are actually fervent preaching witnesses. There, they are even.
