Hitler said that any Jewish blood (whatever that means) in your ancestry meant you had to sew a yellow star on your clothing. In South Africa any Black ancestry subjected a person to the mandates of Aparthed! And at one time in this country anyone who looked as though there was African ancestry - or Carribean ancestry - created a risk of being lynched. In Joe Arpaio's Arizona looking Hispanic subjected you to harassment. How come a drop of blood in your ancestry makes you subject to sanctions & humiliations but not having enough of a proportion of that ancestry divorces you from the so-called privileges of that ancestry. Talk about a schizophrenic notion!!
