In what ways is race ‘real’, and in what ways is it ‘not’, according to these authors?

On Omi and Winant and Duster (you might also want to reference Conley from earlier):
1)  What is similar in these authors’ discussions of race and ethnicity?  What is different?

2) In what ways is race ‘real’, and in what ways is it ‘not’, according to these authors?

I want you to reply to classmate’s post who address question 2. See screenshot.

I’ve also attached the discussion format example like how i should reply to classmate.
