Homogeneity of the human race is not desirable until the peoples of an evolving world attain comparatively high levels of spiritual development.

Homogeneity-the same in structure,quality,etc.;similar or identical.

This line came from the book of Uranchia, anyone familiar with this book? This book details a long line of how the races started, how they interbred, how they(or we)killed each other off, and how we evolved and formed new races. This book could possibly blow some people away, being the claim of the first color of races were-orange, blue, green, indigo, brown and yellow. Maybe red in there, but what-ever, my point is racial discrimination goes way back to the beginning of evolution, and the fight for land, food, creating a more advanced race.
So, if you would choose to look at it, as an Uranchian point of view, racial predjudice was and will be until that enlightened race evolves.
OK, with that said, carry on!
