On those who brought out that lots of religions allow it's adherents to vote. The reason this is a key issue w/ the WT though is because those other religious organizations are very broad and not controlling.
Those other organizations don't control every little aspect of it's adherents lives. The WT goes as far as how loud to play music at weddings, how many should be invited to a wedding, what board games are acceptable or not. Voting is a BIG THING. ANd for a religion that is God's direct channel, they can't be telling people God's will on using 1 paper towel at meetings and not able to give direction on God's will for voting should the members be allowed. It would show either A. The GB fear man and reprecussions for giving an answer like they do for everything else. B. If they don't have to lead on that, then why are they leading on everythign else in their lives?
The field service time reporting is a very good point I hadn't thought of.
