The left is functionally, diagnostically and measurably insane. What is most worrying to them at present, is the fear of defections by people who have a modicum of “self-observation” and bolt from the left’s inability to engage reality with the tools of lucid cognition. At some point their failures will result in a monstrous illumination and they will go suicidal, bringing the rest of us along on their dead end existential train wreck.
I suspect that train has already left the Track. The cars just have not turned over or hit the river yet.
