Good Topic, Frenchy.
Can't add much thus far, just some thoughts. IMO, demanding religions like the WTS define what a cult is. The leaders of the WTS, for whatever reason, have decided they have the truth. Since they think they are God's chosen, they somehow believe that they have the power to demand strict allegiance to their cause. I'm still not sure if the GB REALLY thinks they are chosen or not. Maybe it's just a career to some, and a traditional way of life to others. Nevertheless, they have a corporation to maintain worth billions. Support of the r&f is paramount to this org.
Being deceived and having the proof of such is the main reason for my anger toward the WTS. I didn't even leave because of what they teach. I left because I was stressed to the limit. It was only after my period of research that I started to get angry. Much expectation was heaped on my shoulders by the WTS and the local cong. Having an "unbelieving" mate and three small kids made it difficult to maintain a balance in my life as a JW. Should I give more attention to the "kingdom interests", or to my family? Too much attention to the cong. brought suffering to my wife and kids. Too much attention to the wife and kids brought chastisement from the cong. I simply couldn't hack it any more. I didn't want to give up my duties and just sit at the hall, knowing how others would think of me. So I walked away.
Fortunately for me, most of my family were never JW's. I had an instant support system, and no one was angry at me. They accepted me after I left the cong., and didn't judge me. I truly feel for other JW's who didn't have a built in support system. That's another reason that angers me about the WTS. Vulnerable people that were tossed out without any support. How can a religion expect a person to accept the punishment when the person doesn't believe in the reasons he/she was expelled for? If a person is having doubts, maybe they can ease out, and start creating a life outside the WTS to make an easier transition. Many different scenarios to consider.
