They really shouldn’t, though. The left can’t allow a civil war to start. The reason: Once a serious civil war is underway, this country will become a dangerous and unpleasant place to live. That means that
invaders immigrants will leave by the millions.
The left, dependent on an ever-rising flood of immigrants for votes, can’t afford that politically. They need this country to be a safe and pleasant place to continue to draw immigrants. As soon as it becomes less pleasant, immigration will stop and the ones already here will go back home.
And it’s not enough for it to be a little bit more pleasant than the immigrant’s homeland. It has to be significantly more pleasant to overcome the chore of moving, the risks of moving, for those coming here illegally, and – for those who don’t plan to just stay in their own ex-pat community – the costs of learning a new language.
By the way, some non-leftists will also hasten this by going after the sources of welfare once the chaos of civil war is underway. I predict they’ll disrupt and destroy welfare payments in various ways, and the benefits of being here will plummet while the costs and risks skyrocket.
This will be fairly easy to accomplish once the civil war has broken out; cops and army guys dealing with a rain of bullets from rooftops at city block A are not going to prioritize that fact that someone broke into a welfare office at block B ten miles away and destroyed all its computers.
However, I doubt there are still any people on the left who have thought all this through. If not, then they’ll keep provoking the civil war they think they want, they’ll get it, and a significant amount of the expulsions that will be part of the war and its aftermath will already have been done by the “immigrants” themselves.
