Identity issues (and related notions of identifying people) are concerning to me. I am biracial and find that many of the codifications and terminology used in the everyday processes of idenitification are disturbingly inaccurate and often harmful.
There are not many ethnic, cultural or personal categories which are wholly positive in their application and impact as identifiers. The words we use to define ourselves (group affiliations) are also the tools with which we think about identity.
The problem is that some of our group definitions and terminology (and therefore our thinking too) ends up being contradictory and in conflict. Where we can see some danger in this problem is when people feel driven to extremes of identity, becoming radicalized in different kinds of ways (socially radical, religiously radical, politically radical).
This feeds into the situation of polarity and polarized social politics which seems so intractable sometimes.
The solution is to change our thinking by changing our language about color, ethnicity, race, sexuality and the various "basic" group-based distinctions which drive our thinking on identity.
This does not mean that we should be more politically correct in reference to one another's group affiliations but instead simply choose to be even more basic in our references, which means being more expansive in our identifications.
People can be dark skinned or light skinned, without being folded into an ethnic category. People can be speakers of certain languages, without being ascribed to a nation or religion, etc.
Anyway, that's an issue near my heart, though it may seem absurd to most people.
