Phew! Very, VERY perceptive. You sound as tho you are familiar with the late child psychiatrist, Dr. Frances Cress Welsing. If not, you should be. Videos of her are all over the net.

For 40 years (or more), Dr. Welsing argued and wrote that what "white" people fear most and first is "genetic annihilation." That is, just as you say, they know and understand better than anyone else that they are the world's true "minority" group; that melanin is a dominant gene/molecule over and above "non-whiteness"; and that if "whites" "co-mingled" with melinated peoples, well...soon there will be no more "white people." That's why for centuries in "the West" a black man would and did get more prison time for "raping" a white woman than for murder.

This idea explains and supports much of what you have said here.

Thanks for reading/responding.
