I'd encourage you to read the link instead of whatever kind of dismissal this is. They have leaked correspondence between Stephen Miller and Breitbart coordinating the latter's coverage with an explicit nationalist bent. Breitbart relies on Camp of Saints and VDare for their sourcing on policy stories. Have we already forgotten their "Black Crime" news tag?
They literally had a section on their 'news' website called "Black Crime" - the terms are synonymous. It's astonishing to me that the crowd would rather parse SPLC's phrasing or history rather than the documentary evidence that there are white nationalists making policy at the highest levels of our government and coordinating with one of Facebook's 'approved news sources'.
Well, taking the maximally-charitable view of things would point out that "Black Crime" would cover ~half of violent crime in the US, and so deserve a category. But somehow I doubt that they'd cover non-black crime to quite the same extent. (Though the maximally charitable view there would be that non-black crime is better covered on other sites than black crime is, and so on)
