The greatest challenge of all? Most people inside high control groups don't want to leave. That includes JW's.
Now that we've left that may seem mad, but there you go. They simply want to stay in. Experience shows me that you have to play a waiting game.
It's frustrating but unless people are ready to 'wake up', any campaigns will be viewed as persecution and be seen as proof of how right they really are.
It's an Orwellian world in there.
