There are many forms of nationalism, but I'd like to center upon four particularly popular formations:
Ethnonationalism
>the idea that only a certain people, ethnicity, race, are members of a nation.
Propositional Civic Nationalism
>the idea that anyone, given enough paperwork, can become a member of another nation
Ethnogenesis civic nationalism
>the idea that a nation has an ethnic founding block and people, while sometimes allowing for non-ethnic integration via a quasi-propositional civic framework
Propositional universalist nationalism
>the idea that national identities does not require paperwork and that anyone can become a member of the nation; similar to propositional civic nationalism
Propositional civics and universalists differ in the means by which immigrants are granted/acquire citizenship.
The universalist ordeal of "your country's identity is not real, therefore, we can insert everyone" subverts, in one regard, the propositional civic nationalist premise into a corporate, an organized supra-collective separated from the original citizen body, utilitarian construct designed for elite global influence. Economies are manipulated by collectives of foreign ethnic blocks who are were not raised in the same principles of the nationalist. In another regard, it also subverts the ethnogenesis civic nationalist position, through eroding early migratory, exploratory, and civilizational building phrases as modernized justification for constantly influencing demographics qua economic and political manipulation. Naturally, propositional universalism is an enemy and seemingly at odds with the three other popular forms.
Political phraseology which reflects the deconstruction of ethnogenesis national identity into building patterns is, innately, ethnically genocidal with its instrumental application. The propositional universalist position is an anti-nationalist and anti-ethnic dissolution which results in a loss of national heritage and traceable genealogy; since everyone can be (name), then (name) has no function outside of the purpose for the eradication and reshaping of cultural and societal harmony. This deconstructive process of universalist reconstruction justifies taking down "wrongspeak" statues which violate universalist principles, such as tearing down civil war icons. Because anyone is (name), then what offends and is not everyone must be remade into anyone-name. Systematically, the propositional universalist is at war with any native population of any given society. In fact, the procedure does not stop at any given nation, such as the USA and Britain. All nations are, and will be, subjective to this ontological re-definition of phenomenological experiences, where what you are is now just another name for everyone else. Not only does the propositional universalist declare that identity is essentially meaningless, nation and culture is meaningless. It is, at one point, a universal nihilism yet, at another point, it is a hyphenated moralism of a collective into an ever-widening expansion of the all-humanoid; for what happens, to the propositional universalist, if we were to ever meet another alien species capable of intelligent conversation? Logically, the universalist is at war with even that which we have not yet discovered, and at war with every native of any nation around the world, being for the open redistribution of even citizen identities and the ethnic replacement of any native population.
By inserting culturally conflicting demographics, including ethnicities and religions, the universalist creates a distorted hodgepodge of tensions whose interaction inevitably creates chaos and destruction while enabling rape, economic theft, and the replacement of natives through the subverted protection of foreign interests. Citizens who notice replacement are defamed as hateful for not submitting to institutionalized and international warfare. The result of propositional universalism is a multi-front war of democide, demographic genocide, and cultural re-distribution.
