A race is an arbitrary category based on ambiguously selected similarities observed by some individuals. Just like ethnicity and nationality, it's a collectivist term to describe a mental invention of groups, that is not discovered objectively. By falling into the trap of describing yourself by such groupings you are essentially denying the unique meaning and identity you create for yourself. Why would you want to trade who you are for something created and often times forced by others?
When people attempt to discuss “racial issues” what they are really trying to get at is the socio-economical aspects of certain communities wherein many different types of individuals whom may or may not share certain qualities, cohabit with one another. It's thought to be the idea of race because it's just easier to give a designation to someone based upon physical patterns than trying to see someone as an individual. Laziness keeps you satisfied with this understanding freeing up room so you don't have to deal with further thinking—in this case about strangers.
Race then acquiesces to lowest-common denominator of group identity. If you insist on using false categorical identity at least use something a bit more accurately. What actually separates groups is not if they are white, black, or any other superficial appearance, but rather their cultures and living conditions. And even this is uncertain as similarities between people don' t establish identity.
Often times you may note certain behaviors are common with the populace and it happens that many similar looking types are to be found within this established group. Being inclined to generalize, it becomes easy to fall into the illusionary realm by thinking people are made up of different races with objective criteria to distinguish one another. No such thing can exist, as man is differentiated by characteristics peculiar only to one not shared by anyone else. If you really want to end racism along with majority of social problems then you would see it as a non-issue, meaning recognizing that it only exits in our minds and that real identity is the individual.
