You make a good point here. Most of us, myself included, want to feel like we belong. I think it all depends greatly on the tribe itself, and whether it's a group of kind and open minded people, open to change, or rigid and exclusive.

Lots of people benefit greatly from having a group of friends with one or two things in common that gets together regularly. I've been one of those people myself.

I guess, and I'm only speaking for myself, I'm talking about a different type of group. The most notable difference being in the name as Fuzzy mentioned "clique" "Tribe" often starts out on the surface as being a group of friends with a common goal, but quickly turns into a "clique" with little room for change,and critical thought....that's not a good thing for anyone in my humble opinion.
