Very interesting! Only the WT can use a chart like they did above and in the same breath deny any sort of clergy/laity distinctions.
I suppose if they wanted to be more sneaky about it, they should not have listed the entities top to bottom. Perhpas if they had publishers at the top, GB in the # 3 position, etc, they could have claimed that they were just listing the types of people and groups that exist in the WT.
