Reaction to Shreeve "Terms of Estrangement"

His main idea about race is the difinition or use of race is different from person to person. As the evidence, the last sentence of the article says "What you make of race depends on what the question is, and who wants to know (Smouse) Also, he refers to people's opinions from many kinds of jobs(police officer, anthroplogist, medical researcher)

I think each of us should decide the definition of race because we must think about it by ourselves. Also, there seems no clear or answer to "race". However, the term of "race" should not be used to discriminate other races or look down some people.
About Shreeve's idea, I think he should say "his" opinions about race and should not write only other people's ideas. Also, he could say more why ideas of race are different from each person.
