talks" on Sunday are generally appropriate for all ages. When an Elder is giving a talk and words in the talk such as RAPE & ADULTERY & INCEST are used....sorry but I don't think those are words that should be used in the presence of small children.
I agree. Those of us who grew up in the truth and heard about the horrors of the comming persecution we'd be undergoing and the destruction of all our school mates and neighbors or even ourselves if we didn't tow the line. We'd return from the meeting with a head full of fear of the future.
At one Sunday Watchtower study I recall a little girl raising her hand and giving us all a rundown on the difference between Circumcision of the heart and literal Circumcision. I often wondered what a visitor might think hearing a child talk about such matters.
