I don't think I have ever seen anyone doing that. And I've seen a lot of people, that people like you, CLAIM are "white nationalists" or "White Supremacists" or even "nazis".
I understand your concerns with people being unfairly characterized as white supremacists or Nazis because they happen to be for the uplift and fair treatment of their people -- sort of like how those who argue for fair treatment of their people in the criminal justice system tends to be unfairly characterized as being against the police or against America for that matter.
So in the case of the speech writer, just because he has a strong affinity for Martin Heidegger doesn't mean he is a Nazi -- he even admits that Heidegger's Nazi ties were troubling -- but here is the thing
Lee Atwater set the playbook long ago when he said racists can no longer be overtly racist, that will hurt you -- since MLK and his Civil Rights movement defeated the age of the overt racist -- Atwater said that you have to be more covert, hidden, more coded. So just because some white nationalists don't openly say N-word this, N-word that -- doesn't mean they don't find more coded ways to push out their racist beliefs under the guise of "free exchange of ideas" or "intellectual discussions"
But when you keep continuously being at events that hosted folks like Richard Spencer, or even the person the event is named after, H.L. Menken who famously
"described Jews as “plausibly…the most unpleasant race ever heard of,” and an educated black person as being a “low-caste man” who will “remain inert and inefficient until fifty generations of him have lived in civilization. And even then, the superior white race will be fifty generations ahead of him.”
Now you personally may agree with Menken, but there are others who are not so enamored with what white supremacists have to say and will speak up about it. Trump fired him, if you feel it was a mistake, take it up with Trump -- I personally feel that Trump WH can't afford many more stories like this so they acted quickly.
