Jeff - I'll try to explain my view & hope this makes sense...
To illustrate - many people have strong political views & join a political party.In the UK where I live (for obvious reasons , I won't say where!) many party members disagree even on fundamental issues with their party leaders. For example , many Labour members , even MPs disagree with Tony Blair on the Iraq war or on his educational reforms. But they don't generally resign from the party because they essentially agree with the "overall" package , as it were.If they do , they either "fade" or occasionally join another party.
I'm a religious person - I believe fundamentally in a Creator God & that he sent His son Jesus to die for us. The moral framework , structure & basic doctrines of Jehovah's witnesses appeal. I'm convinced that to preach a message worldwide in numerous languages requires some form of organisational structure. All religions have some kind of "human" leadership directing the troops who claim to be authorised by God.
I know there are some witnesses who are dogmatic , think the society is "wonderful" & hang on every word , just as there are political party members who are "worshippers" of their leaders , as it were. But most are not like that - they simply agree with the overall package.
