Membership of a larger group is not an identity. Being Asian is not an identity. Being gay is not an identity. Being deaf, blind, or wheelchair-bound is not an identity, nor is being economically deprived.
If we embrace narrow group-based identities too fiercely, we cling to the very cages in which others would seek to trap us. We pigeonhole ourselves. We limit our own notion of who we are, and in presenting ourselves as one of a membership, a representative of our type, an ambassador of an amalgam, we ask not to be seen.
