Read their publications--Takimag, V-dare, Daily Stormer, The Right Stuff, Right on Radio--the key component is white identity. What exactly this means is still debated but at bare minimum they wish to see a return to pre-1965 demographics.
There are cross over groups--neoreactionary, nativism, basic American nationalism, anti-feminism, traditionalism.
There is a large debate right now over what is considered alt-light and alt-right with many prominent personalities having some public clashes.
Please go back to post 14 and read the link. I could never explain it as succinctly and authoritatively as Watson. I can, however, tell you from firsthand experience that he’s right.
The only one of those publications I’ve accessed, is V-Dare.
It has been a long time since I have. I have a slightly negative view of it. Now that may be reasoned, or I may have simply lost track of it over time. It may not be problematic. I remember it being so, a little. Again, my memory may be bad.
As for returning to pre-1965 demographics, that isn’t any more racist than some folks wanting the U.S. to become something different by plan.
Gray Davis celebrated the day Whites became less than 50% of California. That was clearly a racist action.
I don’t like racism by any group. My goal is a strong America.
Now, as long as other racial groups like Blacks and Hispanics are going to force the racial issues, I don’t think it is wrong for Whites to advocate for themselves. I will state that I detest being put in that position.
