There are two distinct and opposite ways that 'selective breeding' can be used -
* To produce a healthy race, and to recreate the Divine Order of the Gods through creating different castes within the whole. This is entirely in line with the Laws of Nature because Nature keeps the fittest and most able alive whilst rejecting the weak and useless. This is the method wholly rejected by the society that we live in today.
* There is another method of 'selective breeding' and that is to create a World State based upon the produce-and-consume society, and then to use 'selective breeding' to create a class system able to maintain this type of master-slave society.
We should consider this now in the light of the scientific work on 'Artificial Intelligence'. Before I go into this we need to understand that there was an ancient Aryan Caste System which was based upon the Divine Order and linked to the Cosmos and the Human Body - the macrocosm and the microcosm. This was a natural system based upon the Eternal Laws of Nature. The 'class-system' was an artificial construct. Racial Hygiene is a perfectly natural drive to maintain a healthy Race of Man, 'selective breeding' can be used for other unnatural purposes.
The Laws of God are the Laws of Nature, but when the Dark Lord arose to try to make himself 'God' Nature lost Her sacredness and 'God's Commandments' were there to be obeyed over and above the Laws of Nature. These Dark Powers have destroyed the Aryan Caste System through the promotion of a false 'equality', but what they wish to do is to replace this natural order by an artificial construct which goes against the Laws of Nature.
