Also since i do feel you are sincere in your questions, something to start to really dwell on is the way they speak about things. Often referred here as "double speak". Not that double speak makes you a cult in of its self, but it lends to things they use to deny being a High control group that fits the model.
Ie; our leader is jesus. When you really get attuned to the way the phrase things you realize they flat out lie about things, or present it in a way that does back flips to make the answer seem correct. Just because they say does NOT mean they practice it. At your baptism you swear yourself to THEM (the gb), if you tell your elders you disagree with THEM, THEY will have you banished.
At the ARC Geoffery Jackson made it seem like he had no idea what was going on, and doesn't have anything to do with policy, in fact other GB member on the stand have similarly played as if they were nobody, but within the group... we know what really goes on, they are calling shots, making policy, enforcing it.
