This strikes me as a common failing of rationality. Personally I've never really noticed it in politics though. People arguing politics from all corners of the spectrum usually know exactly what they want to happen instead, and will advocate for it in great detail.
However, in science it is extremely common for known broken theories to be espoused and taught because there's nothing (yet) better. There are many examples from the late 19th/early 20th centuries before quantum mechanics was figured out. For example, the prevailing theory of how the sun worked used a model of gravitational contraction that simply could not have powered the sun for anything like the known age of the earth. That model wasn't really discarded until the 1920s and 30s when Gamow and Teller figured out the nuclear reactions that really did power the sun.
There are many examples today, in many fields, where the existing model simply cannot be accurate. Yet until a better model comes along scientists are loath to discard it.
This irrationality, this unwillingness to listen to someone who says "This idea is wrong" unless they can also say "and this alternative idea is right" is a major theme of Thomas Kuhn's The Structure of Scientific Revolutions.
I've asked SJs whether there was ever a time in their lives when they thought they were in a group that was satisfyingly inclusive, whether there was some experience they were trying to make more common. Admittedly, I only asked a few people (and with tact set on maximum). The only answer I got was no.
It's possible I was overgeneralizing in several ways, but I was asking because it seemed to me that what I'd read of anti-racism had a tone of "something hurts, it's urgent to stop the pain", but there was no positive vision.
