Since you asked for politeness, I won't make any comments about your typically female attention-whoring. Let's begin with point A :

Race is not only skin color. Race consists of all inherited (expressed or recessive) characteristics that are commonly found in a given human (or animal) subgroup and are therefore distinctive. A common lie of anti-racist propagandists consists in reducing race to skin color so as to make it appear as something superficial and unessential; but actually, there are considerable race differences in intelligence and character (due to gene differences between races) which are reflected in human history and in the daily life of multiracial societies. That's why we are racist.

Intelligence lies mainly in genes and to a small extent in environment. Genes, including intelligence genes, are not randomly distributed, and that's why there are race differences in intelligence.

According to the evolution theory, we've once had the same skin color (even though there is a controversy regarding the exact timing of the separation of homo sapiens races, some believe that they evolved from already separated homo erectus races and some believe that we all came out of Africa as homo sapiens). But anyway; according to the same theory, a long time ago, our ancestors were not even humans, they were animals. Should this mean that we should not care whether a living being is an animal or a human? Should we advocate equality between humans and animals, and even legalize consensual human-animal sex? It just doesn't make sense.

Evolution doesn't take place through "parenting" (there is no such thing as a hereditary memory) but through :

- natural selection (the weakest die, those with a specific characteristic which make them better adapted to their environment survive).

- sexual selection (those who mate transmit their characteristics to their offspring, those who don't mate do not).

Nowadays, natural selection in humans is weakening due to technological progress but sexual selection still takes place (in the wrong direction, as stupid people tend to have more children).

Because there is no such thing as inherited moral standards (notwithstanding the fact that morality is subjective and volatile), even though people from different races do TEND to behave and think differently (with exceptions on the margin).

Groups based on inheritance are relevant because when you build a house, you want to give it to your children, to those who share your blood and not to some aliens sharing your "moral standards" or even your "intelligence".

This is due to biological imperatives (living beings seek to perpetuate themselves), hence the fact that our racism is based on inheritance-based groups (for example : White people) rather than strictly characteristic-based groups (for example : all intelligent people). Otherwise, our racism would be purely idealistic, without a grasp on reality. But if we seized the power, we would try to develop positive characteristics such as intelligence in White people through an eugenics agenda.

To make people more intelligent, there is nothing better than deporting non-Whites, since they are far less intelligent than Whites on average. The next step is eugenics among whites themselves.

As a matter of fact, one of the main vectors of epidemias is immigration (as we can see with the current ebola epidemia in West Africa)...
