The Alt-Right is clearly a movement which has attracted attention from young people as of late. The reason why I believe it exists is for various reasons, but first and foremost is the concept of race, as a biological concept, as property. I do not see this as a bad thing, because race not only influences the inheritance of important evolutionary adaptations, such as intelligence and behavioral traits but also provides the necessary platform for the continued, directed evolution of a closely related group of people. Under the system of Propertarianism, race, as a form of property (I speak of property here as a norm, rather than some mystical characteristic of a thing) would most likely fall under the category of commons. Now this property, for Northwestern Europeans and their relatives in North America, is under threat from low birth rates and the mass immigration of racially different people. It is also under threat from miscegenation.
Race, I believe, has gained importance in the right due to the fact that for many people, it is the only long-lasting, tangible property which they effectively lay claim to, as opposed to something they are paying a rent, lease, or mortgage on. As post-industrial society has become extremely complex, and what property one has today may be very different from what one has tomorrow, the Alt-Right is effectively investing in a form of property which can survive stock market crashes, housing bubbles and more. Race can also survive vast changes in public religious opinion, though often one religion or another will be detrimental for its long-term survival.
So I think that even the members Alt-Right are to be considered sovereigns; they are, I believe, aristocrats under the system of Aristocratic Egalitarianism because they have mutually agreed to protect each other’s property, their race, from outside threats.
