Why would COs or DOs or the GB tell people how to vote ? Anglicans are politically active but my vicar doesn't tell me how to vote .
Anyone can be a conscientious objector and not fight . That is nothing to do with being involved in politics. That is up to individual consciences.
Those are not valid reasons for non involvement in politics. As with most JW dictats it is to do with control and keeping Witnesses away from non Witnesses.
