I spent enough of those monthly visits with the ones around here to tend to agree with you. On one hand, they are dedicated to a very decent life and incredible morals and personal habits. On the other hand, they expect those who adhere to JW to accept their interpretation of the Bible and how they lead their lives without question. In the US; they're mostly a mild nuisance or respected from a distance. I could understand how in many countries their putting their principles above the law and the culture/values of their country could be bothersome.
I came from a JW family, and you can ask me or many other hundreds of thousands, if you have been on the inside, it is a cult.
