Of course, here we should probably acknowledge the need for magical pixie dust to get the civil war going. While I can certainly see a great deal of violence, as the south has a bunch of riots and the Government heads towards confrontation with Radical Unions, it has not built up to anywhere near the point where Youd get a civil war. Anti-Lynching is bad for the South, but it's not like we just went full 1960s on them, they still retain Segregation. They wouldn't have the stomach to actually go through and shoot people over this. In the North, Radical Unions are sure angry but I doubt it would be enough to actually do a Civil war. they dont even have Moderate Unions on their side, let alone the majority of citizens in the states. What should follow is a nasty rash of Political violence, with some highlights (deploying troops south, crushing the reds) but not an actual civil war.
