Caste, the 14th Amendment, and overcoming white supremacy

I just listened to a recent Diane Rehm show, Two Views On The Jim Crow South And Its Legacy, this morning. She interviews Charles Dew and Isabel Wilkerson.  From Professor Dew, I got some answers to questions I ask myself every time I see an old picture of a lynching.  From Professor Wilkerson, I got angry.  Not about what she said, but how her discussion recalled for me our 14th Amendment doctrine and its modern colorblind interpretation.  The moral equivalence of, say, Blacks growing up under Jim Crow and whites applying to college, escapes me.  If that's what the 14th Amendment really means, I am fully prepared to give it back.
