I am surprised when people say they have studied for 3 6 9 months. I didn’t think there was that much material. Take away the boasting and slandering , do they really say anything?
I have never met a JW who knows more than 12 or so verses and a prepackaged sales pitch on trinity, hell, no fighting in war, ex members are bad.
I have had discussions with Elders who I don’t even feel would be capable of teaching a Sunday school class.
