It was during a discussion of the Leo Franks trial.
The north hailed the case as a landmark -- The first time a black man was allowed, in court, to testify against a white man.
The south (This was about 1913) openly laughed at the ignorance of the north. To them Leo Franks was not a white man, he was a Jew.
Me, being the person I am, went over to some Jewish people I knew and said, "Okay, you look like a bunch of honkeys to me. What do you think you are."
They told me all Jews descended by blood, such as they, were of Middle East descent, even if they converted to Christianity. However there are people of non Jewish blood who have converted to the Jewish religion.
