I jumped down that rabbit hole.
The source of his link is BET. BET sourced Vice News a vice news article.
Now BET and Vice both do us a service of pointing out how rioting and looting is being done by people of both races. The question is why- BET references Vice in saying it's Far-Right, White Supremacist, etc, but the images only indicate the men and women are white. It's like assuming every black person who riots is a disciple of Louis Farrakhan. One of the final tweets referenced in the BET article shows white members of the militant communist organization, Antifa.
The right-wing white protestors mentioned in the Vice article are mostly extreme civil libertarians. Whether they are Right Wing is a matter of debate even in Right Wing circles. But even if we give the devil his due for a moment, they are not really white supremacists and, it appears, not doing very much in the way of rioting or looting. If anything, their presence has prevented a lot of violence in their immediate vicinity.
So that covers one end of the vice article. The other is speculative trash at worst and provided no evidence of "accelerationists" and "eco fascists" on the streets. Just a message board post.
In short, these articles together in no way prove there are many right wing rioters and looters afoot. The evidence they provide tells a different story even without the commentary.
Judging from the sources provided by
@posthuman in another thread, it looks like many of the rioters/looters are white, right wing extremists.
