I saw the presentation as matter of fact, or as a footnote down at the bottom.
Just mentioning the word doesnt make it graphic. If they go into descriptions then I would understand your concern, but just mentioning it, especially in the timeframe we are in now, is not innappropriate. I am a teacher and you would be astonished what sort of conversation goes on between 11 year olds!
I would much rather have them educated in a religious setting rather than by thier peers. Too many times people are so uptight about things they make it more appealing when good ol teenage rebelliousness hits.
I have always thought the best approach is to be honest and straightforward about any topic. I have read through most of the articles on this subject matter and dont find anything highly offensive.
Perhaps you can provide a sample of what you found offensive?
That being said, every JW is supposed to prepare for the WT article ahead of time, so they always have the option of missing that meeting if they think it is not appropriate.
