You are projecting your own beliefs and assuming most people agree with you.
I don’t think it’s a given that people here necessarily agree in their opinions about the Watchtower organisation. There is a whole range of views on that topic, as on many others, which may only be obscured somewhat by the fact that a small number of posters are loud about expressing their views, while many others, particularly those with views that are in the minority, don’t bother expressing views that will simply be shouted down anyway. I know of posters who believe in God and some who believe JW beliefs to varying degrees, but are not interested in entering the type of combative discussion this forum tends to offer on these topics.
Plus there are people arriving on this forum fresh from the KH every day. So to suggest that everyone here already agrees that Watchtower is wrong, and the only thing left worth discussing is whether the Bible is true and God even exists - is wide of the mark.
