DY, I admit I haven't seen the video (I really can't stomach watching the videos) but I had the same thought:
Move forward with your life and let others live theirs. Much happiness and peace comes from minding one's business only.
So, my question to the JWs would be: Is it appropriate to teach younger children to tell school mates their parents are in a relationship that doesn't merit "paradise"? This would be my problem with a video like this (along with the homophobia, of course).
The JWs think they have a right to tell other people how to live their lives. That is an integral part of their culture. The first reason in my mind that made me leave the "org".
Talesin, I know of a situation (possibly two) of a suicide because the young person couldn't "meet the requirements" of the "org". My sympathy to you about your friend.
