Sure, there are different tribes, and different personalities. Let's assume that an "average tribe" is... well, average; not very abusive, but also not perfect.

I think some people, if given realistic free choice, would prefer to live in that tribe, and some people would prefer to live in an individualist society. So let's say the former are "voluntary tribesmen", although they may have bad luck and end up in an abusive tribe. The latter, if they live in a culture that does not give them a choice, are "involuntary tribesmen".

From the outside, the "voluntary" and "involuntary" tribesmen may look the same for an observer from our culture. Both stick with their tribe. But one of them enjoys it, and the other one only does it to prevent starvation of themselves or their relatives. Just because we sometimes feel that we would enjoy living in a tribe, we should not believe that all people living in tribes are of the "voluntary" type.
