That would be the best thing to happen not just to the American left, but the world as a whole. The current situation is such that a bunch of narrow-minded provincial jerks and homophobes in rural and suburban Amerikkka make decisions that influence people around the world in countries that these dickheads cannot even find on the map. Civil war and destruction of the federal entity would stop that and thus it is a good thing, from the world's point of view at least.
