I'm talking about liberals in general. For those of us in the U.S., there's no conceivable path to a mass movement that doesn't involve bringing millions of them around to our side. This means learning how they think is important, as is giving them a path to leave the Democratic Party and move left.

Most libs believe their own bullshit -- it's West Wing brain, we talk about it all the time. They aren't cheering on horrors only to cynically cry about them when they think it's appropriate; they really believe the shit they see on CNN or read in the Atlantic and have the object permanence of people comfortable enough to consume politics like they do sports. They don't scoff at evidence of horrors because they support those horrors; they reject it because it deeply challenges the fundamental tenets of their worldview (i.e., that the U.S. is a good country). This is dishonest and cowardly -- they're libs, after all -- but it's not knowing exactly how the sausage is made and then perpetually lying about what they think of it, which is what you seem to think is going on here. My point is that this misunderstands how libs usually think.
