I've always considered #identity, much like #knowledge, an #individual's own, personal, tacit, unique attribute, evolved through a lifetime and representing the history of all social interactions they had with their environment.
I find the modern #identitytheory focus on the many #social "identities" (father, golfer, employee, etc ...) one has during the day, wrong.
In my view, these are just external #roles one assumes and plays in different #systems they are part of. They may define #what an individual is but not #who they are.
In fact, I believe that it is #who an individual is that affect #how they do #what they do in the role they are given.
I also consider the largely accepted academic #theory presented in the attached document as the direct cause of our present dysfunctional society marred by #identitypolitics.
