Very interesting observations. I also note that the ones who seem to be "zealous" are usually in pursuit of or trying to hold on to priveledges. Their zeal does not appear to be real. Its all about the status of being used in some compacity. If you are a brother you want to appear to be "zealous" and theocratic because you want to be a ministerial servant or elder. If you are a married couple you want to appear to be " zealous " so you can be used at the circuit assemblies or even asked to serve in the circuit work.
Take away the privledges and how many would keep up the appearance?
