I am reminded of evidence I have seen from ones in early childhood. Examples being:

My child, when still a baby not yet ready to walk, went to touch the hand of a little white boy around 2 years old, who immediately drew his hand back away from my child and screwed his face up in disgust and said, " you're black". As if the white child would get a disease.

Why do natural differences make such an impression on the white race?

Another white child approximately 4 years old told my other child, who was the same age and who usually played well with these kids, "Why aren't you white like us? you're supposed to be white not black"

Just a few examples of how I am convinced that it is their nature to first notice the separateness and differences between the races and then later, when they are older, act negatively upon the knowledge of those differences.

If mankind was trully meant to lived in a mixed amongst the races, then all these racial problems would never have surfaced nor lasted so long. Some chose to believe otherwise but racism is not dead.

Thus, to answer your question, for the type of racism that you mentioned above to end, the race responsible for the perpetration of said racism throughout the centuries would have to be destroyed.

A few individual cases of well meaning "rastas" or other whites does not change the bottom line results.

Case in point is this board, where we've seen racism rear its' ugly head out some of these self-proclaimed liberated white rastas.

It's an inborn disease that 99.9% can not escape or heal themselves from.
