Discussion with Large Groups

We have the happy problem of having too many kids. It makes 
discussions virtually impossible, but other than Wink and Capture 
the Flag, it's what the majority of youth in our group want on a 
Sunday evening.
Here's one technique that would work well with any number of kids though, and it's a nice change from the circle or fishbowl. Have each youth write down a controversial situation. This could be 
anything from the Iraq war, to having a friend who makes racist or 
homophobic comments, to being in a situation where alcohol or drugs 
are being used.
Put a long piece of masking down across the floor of your room, and label one end AGREE/APPROVE and the other DISAGREE/DISAPPROVE.  
Have youth exchange papers with one another, and ask for 2 volunteers.
Have the first volunteer read what is on his paper. Ask the second
volunteer to take a stand on the tape line which represents how she feels about the situation. She should explain why she chose the position on the line which she did.
At that point, the rest of the group is invited to give arguments (pro/con) or make comments about the situation in an attempt to change the mind of the person standing on the tape line, who will move and respond to comments from the individuals in the group if she feels so inclined.
Continue until it's boring, then choose two more volunteers.
This isn't only an interesting way to create a vibrant discussion, it's also a good chance for youth to see peer pressure at work, to find out what "moves them", to see the influence they have on others, and so on.
