What you are suggesting is more akin to White Nationalism, Ethno-Nationalism, White Id-Pol, Isolationism, White Supremacism et cetera. The term "alt right", as coined by Spencer himself, does not describe a single, coherent belief system, but rather a cluster of different converging ideologies.
First off, the alt right finds its niche as a more radical alternative to traditional conservatism. The true roots of the alt right however are decidedly European, it was the Nouvelle Droite and Bloc identitaire in France that served as the biggest inspiration for Spencer. He himself often claims to actively be in contact with the ID movement in Europe. At the center of the ID movement is a core belief of the superiority of European culture, not of the white race. It is therefore cultural supremacism, not white supremacism. The core distinction here is the concept of "Ethnopluralism", the belief of separation not by ones skin color, but by ones 'cultural affiliation'. (Note: These people are as racist as it gets, but they decided to cloak that to avoid persecution). The roots of ethnopluralism are "völkisch", that is to say they are not a direct product of biological racism, but rather a stray bullet of it.
Furthermore, alt right far surpasses the aspects of white Id-Pol that you mention in your post, some other core tenets are a rejection of: Feminism, Liberalism, Marxism, Political Correctness, Migration (unless it's whites migrating elsewhere..), Homosexuality, Transsexuality, "Degeneracy", "Zionism" (most, not all of them, are raging anti-semites), Multiculturalism and so forth.
I mentioned the
nouvelle droite and its influence on Spencer specifically in another post. I’m familiar with the Identitarian movement, and am in touch with some people in
Génération Identitaire. But I don’t think one can say that the alt right is just a
nouvelle droite transatlantique, since it’s very American in its makeup and, obviously, its influences.
To consider your list of things the alt right rejects:
Feminism – Yes, but so do plenty of others. And alt-feminism is kind of becoming a thing, too.
Liberalism – As above, though of course some argue that liberal politics and ideas are only possible in white societies.
Marxism – Most people reject Marxism.
Political Correctness – Yes, but so do plenty of others, perhaps a majority.
Migration – Yes, but most Europeans are and always have been against mass migration.
Homosexuality – Debatable, considering that the alt-right has some prominent out and proud homosexuals (Greg Johnson, etc.).
Transsexuality – Yes, but so do plenty of others.
Degeneracy – This seem to be used mostly as an insult when disagreeing and means whatever the speaker wants it to; it’s the alt right’s ‘racism’, if you will.
Zionism – Very debatable; indeed, many people in the alt right see Israel as a model for the kind of ethnostate they want.
Multiculturalism – Yes, but so do plenty of others, perhaps a majority.
I was looking at what sets the alt right apart, so there seemed little point in mentioning things that people of diverse political persuasions, or indeed the majority of people, reject. Someone could reject all the things on your list and not be alt right, in my opinion. White identity politics, on the other hand, is central.
Nice smug ad hominem at the end of your post by the way, almost went past me. But let's try to keep this discussion amicable and impersonal, right?
That’s just your own paranoia I’m afraid.
