Hi InterestedOne and welcome!
Your perceptions of this organization and its subtle methods are spot on. They are masters at the double-speak and loaded language and your ability to ask deep questions and see through the the vagueness is unnerving to them. Keep doing what your doing. Go in to your study armed with knowledge from excellent websites like jwfacts.com and freeminds.org. Nothing alarms a Witness more than someone who knows more about their organization than they do. You may even help your "teachers" to think more rationally.
But be warned. If you keep asking deep, involved questions your teachers will start to back off and declare you "not of the right heart condition to accept the "truth"" or "too intellectual and not humble enough" for it.
In other words, you're not stupid enough.
Good luck, and well done.
