I've not heard of reified postmodern theory. - Sound like a bit of an oxymoron.
I believe it means postmodernism as applied in social movements like Wokism, rather than just as an academic tool.
For pretty much everything on the list applying it in the real world breaks it. They are oxymorons.
If everything is a social construct and there is no universal truth, how can postmodern theory be a universal truth enforced on all?
If you believe society is implicitly based on some power pyramid, so you create a space within it where you explicitly invert the power pyramid to "cancel it out", and you're in charge in that space, then all that stuff about who is supposed to have power no longer applies in your space. You need to update your "privilege" table and reverse the pyramid again.
And "queer theory" is all about rejecting the establishment norms. Once queer theory becomes the establishment norm, you have to reject it by its own principles.
And same with "trans women are women". If they are, and that was really anyone's association with "women", then the whole thing they're "identifying" with would vanish. They need "woman" to still mean "female" to anchor the "wrong sex" feeling. They don't want to identify as "Alex Drummond".
So it is oxymorons all the way down, which is why none of it works.
And I think the applied postmodernism is the battering ram which forces all the oxymorons through - it fairly consistently says "I reject your "reality" and "empiricism", they are just your verbal pretext for exerting power. I'm going to fight back with my own words, making this a straight verbal power struggle." And the above oxymoronic tools are used in that fight.
Once you go down that path of course, you're worse off than when you started. Previously if a bully wanted to be in charge they had to combine it with some convincing arguments. Now it's just the biggest bully wins.
Someone linked to New Discourses above - there are some good videos there, and audio podcasts. I think Helen Pluckrose might be a good place to start for the OP's questions:
The Evolution of Postmodern Thought
In her talk, she develops the definition of “Social Justice” as it is used in the academic literature in this tradition, explains its connections to identity politics and the political correctness movement, and then shows the relevance of the original postmodernists to this Theory in some detail. She does this to elegantly describe the progression of these ideas from Theory to activism to the streets by describing how these ideas originated, evolved, and were built upon by successive generations of Theorists leading up to those who have become famous names even outside of the scholarly world today: for examples, Peggy McIntosh, Barbara Applebaum, and Robin DiAngelo. She wraps up by explaining how this newest generation of Theorists simplified the highly abstract ideas of their predecessors and made it far clearer and easier to understand so that it could, as we now see all around us, eventually go mainstream.
