You really think one must follow policy even if the top leaders are wrong? Do you really think the comparison to the military is a proper one. And as you note, a member of the military is obligated to disobey illegal orders. Certainly wrong orders may still be legal so yes a member of the military should obey a wrong order. Still I do not like the comparison. Church membership is not the military. The old teaching from I thon Heber J Grant that one will be blessed for following the prophet even if he is wrong, but don't worry, the lord would take a prophet before allowing him to lead us astray. How did that work for the priesthood ban? You admit it was wrong so I guess leader can lead us astray right?
