she doesnt like ppl trying to modify her thoughts
This sounds all too familiar, it's the motto of my wife
As Heaven said, that's exactly what the society does, and they don't have any problem with that. The "Truth" as they call it can be summed up nicely in this: "anything the GB says". If you touch a doctrine that the GB teaches, you're questioning that "Truth". The doctrine in itself is not important, it can be changed at any time, but only by the GB, to keep up the "Truth".
