what's missing is the nature of power in the construction of identity.  structures of power influence identity as well as identity influcences power.  without inclduing power identity construction mistakenly resides in a nuetral dynamic somehow transcending power.  in regards to multiracial identity it could be possible to be both asian and black if we disregard the complexities of what it is to be asain and/or black and if we disregard the binary nature of power that demands an either/or choice.
