You know it seems that the best small groups are formed naturally. A group of friends sitting around discussing issues and united by some common bond. It works sometimes the other way(forced) if the group's purpose in meeting is important enough to hold the group together. And of course there always needs to be weeding and pruning of the group. I have found that in forced groups some people need to leave and find another group and some groups will need to intentionally look for some key people to join their group.
You know I wonder if things like the book cover are offensive because people choose to be offended. If those pictures are just caricatures and not your true culture then don't tie them to Asian culture by making such a big deal about it. Now every time I do see one of these caricatures the first thing that will pop into my head is all of this.
Maybe I'm over simplifying it.
