> Abraham was a Gentile before He was a Jew!

The basic premise here is totally wrong; Abraham was *never* Jewish.

- Abraham was Semitic (the great<sup>7</sup>-grandson of Shem).
- Abraham was the father of Ishmael (ancestor of Arabs).
- Abraham was the father of Isaac, who was the father of Esau (ancestor of Edomites, Turks, et al.) and Jacob (AKA Israel).
- None of Abraham, Ishmael, Isaac, Esau, Israel, nor 11 of Israel's sons were Jewish.
- Abraham's great-grandson, Judah, *was* the ancestor of the Jews.

> Since Abraham is of Gentile stock … would this not be sufficient reason … be a basis to resolve the messy situation of Racism in the minds---and hearts---of people around the world?

No.  
(Have *you* had any personal success convincing the world not to hate (using any reason/basis at all)?)

How would you apply any of this to the massive racism in Rwanda in the 1990s, when civil war between the two races killed an incredible number of civilians, despite the two "races" actually being the same identical people, assigned arbitrary labels of "Tutsi" and "Hutu" only a few decades before by the Belgians.

> All Gentiles (ethnics), Abraham and everyone else, are the same flesh and blood people … .

True, but it's a non-issue.  
There is no reason to think the Bible says anything different.
