Those similarities do exist Dude, no doubt about that. The thing I would query is the worship of the pope versus the GB. I personally feel that while Catholics for the most part openly honor the pope, JWs shrink in fear of the GB and it's dictates in a way I have never seen a Catholic do with regard to the pope.

Having traveled a bit in my life I think that there are definite regional differences in the way Catholics follow and interpret their faith, much more so than for JWs who are uniformly united in unison, so that experiences of the life within the faith vary very little from country to country and continent to continent. In other words I feel than JWs worship the GB they are just not even really aware that they do so..........fear/ worship........healthy fear of displeasing God, oops GB. 

When a Catholic leaves they certainly do not treat you as a rebel and a leper and disenfranchise your family rights by decree.
