Douglas Wilson commenting on the culture says,
The central driving engine of all this current pomo madness is the idea that a commitment to fixed, objective truth is itself a Euro-Western form of racism and oppression. …”
This has been my experience of the culture as well.
First. Their “fluidness,” is a revised version of the white Greek philosopher, Protagoras, and his skepticism and relativism. The exception is that instead of public debates of the Skeptics Vs Plato or St. Augustine, Protagoras’ philosophy is applied in a political strong-armed way. I do not use inductive historical arguments, but for sake of argument we are assuming it. The point is that they are using a Euro-centric philosophy to say Euro-centric philosophy is bad. Stupid.
Secondly, they cannot attack objective truth without using objective truth; otherwise, their attack would also be an endorsement of what they are attacking. But if they are endorsing my position, then they are celebrating the fact Jesus is Lord, and they are wrong and under God’s judgment.
For their position to be true it would have to be false at the same time. If they attack my position it would mean their mom is a fish, and all dogs are trees, therefore, all cars are fingers.
In addition, fluidness must be, well, fluid. For example, a position of progressivism to be true, then the foundation of “progress” itself would also have to progress. Maybe it has already done so? And so, for fluidness to be true as a foundational standard, then the standard must also be fluid, so that fluidness might already mean to be rigidness.
Moreover, if they wish to say, all things are fluid except fluidness, and since this cannot be validly inferred from the standard, it would mean they must appeal to a higher first principle to produce such terms and knowledge. Will it be irrational empiricism, that when used with science commits a triple fallacy, and itself also falls into skepticism? But skepticism denies the law of contradiction.
Third. Because skepticism (and all its siblings of relativism, fluidness, etc) denies the law of contradiction, it means their epistemology gives no knowledge period. Forget abstract concepts of ethics, and truth, their epistemology cannot give them terms such as “sky,” “man,” “tree,” or “dog.” A contradiction both affirms and denies the same term, thus, they cancel each other out in an infinite regress. Thus, you cannot affirm or deny anything. You cannot affirm your own position or deny your opponents. It means if they are thinking anything, they are denying their own position. Also, the laws of logic are not only laws of thought, they are also laws of reality. Back to our point of affirming or denying. Skepticism does not allow one to affirm or deny anything, but, to even say this with intelligence, one must affirm it or deny it. They use the very thing their position denies. A more pragmatic example might help. If one tries to deny their own existence, (“I do not exist”), they are forced to use their own existence to do it. Their use of it proves it, despite what their lips say. Thus, reality stops them from doing a contradiction in this world. A contradiction is something that has no being in the mind or in the world. A contradiction is implausible with metaphysics.
Lastly, Christianity has a doctrine of logic, and intelligence. The Bible also says that all others are false, and only God has revealed truth. If they must borrow the things necessary for any intelligence from the Bible, and because it also says all others are false, it means they are false by logical necessity.

 Also, did not this philosophy of empiricism come from David Hume, and thus is Euro-centric? Did not this Euro-centric philosophy drive much of the colonialism, and evolution and science-materialism; but I digress, because I do not rest my arguments on induction.
