Before knowing much about the cult, my first thought was how suppressed the collective feel of the people/room (kingdom hall) felt. It literally felt like something heavy was weighing it down. The experience was very shallow, fake, rigid, controlled in every aspect without anything free flowing, and boring to the point where I caught myself tuning out.
As for the material they presented along with the magazines, major red flags went off. The writings gave an air of manipulation, talking down on you as though you're stupid, along with a tone of control. It reminded me of abusive personalities right away. I bailed not too long after.
