Insecurity with one's race or feelings of inferiority about one's race results in race jumping or inter racist breeding.

It is another form of racism, however, it never gets mentioned as such.

It is not in the best interest of advancing the human race. As long as it has been happening there have been no notable independent thinkers with great minds from inter racist breeding, for example, like Einstein, the Wright Brothers, da vinci, Bill Gates, Galileo, Fermi, and the list goes on and on. However nowhere are there any mixed african/Caucasians with great minds. And truthfully, there never will be.
