Thanks fokyc. I remember reading this a long time ago, didn't pay much attention to it then. Brainwashing does strange things to one's perception of reality.
Now, if I were to answer those questions at the end, I would be hard pressed not to say a firm Yes to all of them.
JWs isolate themselves from friends, family, and even society - see: shunning, worldly people, etc.
They use deceptive and unethical techniques to recruit - one of my biggest problem with them, there's so much they don't tell new recruits.
Cult leaders use manipulative methods - they use fear as the main tool.
Some of their worship is cloacked in secrecy - well, probably this is the only one, where I can't say a firm Yes, only a small "yes". They have things that followers don't know about but they should. Like how exactly does the Holy Spirit direct the GB? Almost no JW knows of the 60% rule.
They are definately following human leaders - all their teaching comes from a group of men. If one finds a teaching to contradict the Bible, he's told to "wait for Jehovah", meaning accept and follow the human interpretation instead of what you understood from the Bible.
