Shooting star - before we discussed it I had the kids write their opinions on paper so they could think about it and not have to verbalize it in public. We just did a show of hands if they thought it was an issue or not. We then discussed it in small group, then as a whole.
You brought up a very good point and that is about trust building w/i a discussion group setting. I strongly believe opinions have to be respected. I try to teach that opinion is strictly that but it needs to be respectful and have substance to back it up. I was pleased in that aspect, they didn't bash each other and they did use examples to back up their opinion. (such as the young lady who contrasted the color red for the loin cloth vs purple and another girl who likened it to "hollywooding" everything)
Just my 2 cents worth. Most often I don't read opinions on articles or blogs because I am very tired of lack of respect, use of foul language and bashing. Hopefully I will reach some kids so they discuss opinion respectfully
It's about the journey and being in the moment, not about the destination
