Your tribe is the set of all people that (a) you consider to be part of your tribe and (b) who consider you to be part of their tribe.

This isn’t a theoretical construct. You can actually enumerate your tribe members from your social graph.

Exercise: to what extent does your tribe correspond to national borders?

Tribes are less geographical than they used to be, esp if you don’t agree with the values prevalent in your geography. Saying this, the propinquity effect, i.e. the tendency for people to form friendships with those they encounter often, is real & stronger when encounters are IRL vs virtual.
