I thought this quote nicely summarizes my opinion on the whole ethnic issue:
"Nothing comparable to the virulent color prejudice of modern times existed in the ancient world. The ancients did not fall into the error of biological racism; black skin color was not a sign of inferiority. Greeks and Romans did not establish color as an obstacle to integration in society. An ancient society was one that for all its faults and failures never made color the basis for judging a man."
