Why are White People Considered Superior to the rest of the Human Race?

I see nothing special special about them.
Logic Explains
Take 2 iphones.
One Black and One White - Would you discriminate that iphone on the basis of hue and colour?
No.
Simple Logic = Racism Explained

Your simple logic has brought about the end of racial discrimination. Who's that ringing your doorbell? Why, it's the Nobel Committee.

"white" people are only "superior" in making vit D in winter.

Who does that? You?

Human beings are much more complicated than the mechanical simplicity of an iPhone.

The way I see this question is based in Darwinian evolution. Human beings are still largely an animal just like any other. We tend to think in terms of what is going to allow us to procreate and continue the species at all costs. If white skin is a great indicator of time spent in the sun i.e. Time spent in danger of the elements as opposed to the safety of a shield from the elements, then it would stand to reason that white people are perceived, in the collective unconscious of humans, to be more able to procreate by means of resources available.

This would also explain why we prefer soft and undamaged skin to rough or broken skin: that it represents unhealthiness and/or a lack of resources to ensure one's own health.

If you ask this question to Chinese they will give you a look and a stare.
