Hi cultBgone. I gotta admit the congregation I was in was largely made up of decent people.
However, there were some with 'scary cult personas'.
My mother could never quit smoking. I had an elder say to me: 'maybe you should give up witnessing to your mum, she's still smoking, she hasn't fully accepted the message, she might not make it'. Translation into plain English: our loving God Jehovah will very soon kill your mother because she smokes.
I was a true believer, 16 years old at the time.
