They might have meant well and I was watching it on Youtube, but I'm with dubstepped and Desirousofchange, this will just reinforce the crazy apostate image and will make JWs close ranks.
They will think it's all part of Satan's attack on them. It won't change anyone, it will do the opposite.
What might be effective is a Leah Remini show with heart breaking stories from exJWs. I cried through a lot of those episodes. That might move people if they watch it. Bursting into kingdom halls, no matter how good the intentions, will make matters worse.
But I do applaud Parker and gang for going up to Warwick. Parker said, he very respectfully went to the gate (coached by Spike R - who is a lovely ex-elder) and asked if the GB would see them. They weren't available so Parker explained why they were there.
I thought it was petty of the bethel to turn the sprinklers on when it was raining.
I was watched it all on live feed on Parker's Youtube channel and Spoonfednomore as well.
Rightly or wrongly these exJws have good intentions.
