I don't know who counts as what - it's pretty confusing, and that's why I just went with Völkisch, since I'm guessing your defining criteria is not really religion or genetics but some mix of culture, ideology, and physical appearance and you know it when you see it and it's loosely German-American.
The thing is, I don't think believe members of the populations you outline actually consider themselves as a tribe, at least not in the ethno-nationalist light that you're using (If they did, there would exist a simple word to describe them). Would you agree that their is a certain artificiality inherent in constructing an ethno-national identity around this group?
It's totally artificial and metapolitically hopeless, just like everything else available to white people in this country, unless they're Episcopalian or something. And the Episcopalians have bigger problems.
As far as I can tell, there is no possible way to solve the problems of identity in this country. Most of the white population is deeply psychologically damaged in a way that is rarely even noticed, and there's nothing anyone can do about it other than maybe join a frat.
Through LessWrong, I've discovered the no-reactionary movement. Servery says that there are some of you here.
I'm curious, what lead you to accept the basic premises of the movement? What is the story of your personal "conversion"? Was there some particular insight or information that was important in convincing you? Was it something that just "clicked" for you or that you had always felt in a vague way? Were any of you "raised in it"?
Feel free to forward my questions to others or direct me towards a better forum for asking this.
I hope that this is in no way demeaning or insulting. I'm genuinely curious and my questioning is value free. If you point me towards compelling evidence of the neo-reactionary premise, I'll update on it.
