Fascists have a lot of murder curiosity, albeit here they are even more cowardly than elsewhere. That being said I would already say there is a rising pattern of fascist violence, in between violence against black people, asians, queer/trans, homeless, hell even a couple shootings because people told them to put on a mask. For a real “hot” civil war to take place in America the entire country would have to deteriorate and collapse IMO, if it happened I wouldn’t bet any time super soon
