The left has a narrative. The narrative is a fiction. The left tries to fulfill the narrative in any way it can, by creating more fiction, even by criminal means, because its world view depends on the narrative. Part of the narrative of the left is that white people are all racists who want to kill and enslave black people. To fulfill this part of the narrative, the left looks for white supremacists and white Nazis constantly. It doesn't find them, because they don't exist -- the narrative is fiction. So the left tries to create them by painting white groups and white individuals as supremacist or terrorist or Nazi or racist or KKK. This keeps the stories in the media flowing, and supports the propaganda that props up the narrative. Meanwhile, white people are getting increasingly pissed off, for real, due to the insanity that passes for the present government.
