But the right-wing white militia here, the Three Percenters, are not necessarily the white supremacists that you might assume, and may not be pro-Trump. Given the demographic of their membership, there are undoubtedly many racists in the group; but see this article that @Senegoid linked recently, and my subsequent comment. They may care little for black lives per se, but their primary agenda is opposition to Federal government, and many of them are not happy with Trump’s recent excesses.
Bizarre as it seems, it’s not inconceivable that if violent Federal action against protesters gets worse, Three Percenters might line out on the BLM side against the Federal agents.
