Dark Matter theories including their subvarients (MACHOs, Axioms, WIMPs, Kaluza-Klein, graviton, HDM, CDM, LCDM).

Those are not dark matter theories in an of themselves. Kaluaza-Klein is an attempt to unify E&M and gravity and may or may not lead to a dark matter candidate. Gravitons are hypothesized spin-2 particles which might mediated gravity.

As for the fudge factor, I am saying that Dark Matter itself is the fudge factor that allows us to fudge the math of General Relativity so that it no longer disagrees with the observational evidence.

Where in GR do you think this fudge occurs?

General Relativity predicts that galaxies are spinning so fast that they would explode

Please present this calculation.

Dark Matter is the fudge factor that that "fixes" the equations to make them return the specific results we are looking for.

Where in what equation does this fix occur?

Also, the only regions where the rotation curves disagree in any meaningful way with General Relativity ARE in fact low acceleration environments

Galaxy rotation curves compare Newton to observations: http://w.astro.berkeley.edu/~mwhite/darkmatter/rotcurve.html. This was the original basis for the discrepancy.

much lower than anywhere within our own solar system and lower than anywhere that GR has been accurately tested...

The discrepancy between GR and anything else in this low acceleration regime is not motivated. In the solar system GR and other metric theories of gravity are well constrained by the Parametrized Post Newtonian formalism.

perhaps you could state your position more clearly

There is strong observational evidence for a body of unexplained phenomena that is due to something we collectively termed "dark matter", since we don't know what it is.

OR that it may not exist and the equations will need to be modified

Which equations do you think need to be modified?

It is perfectly acceptable to say "we don't yet know what is causing this anomaly" but if that is the case you may want to review how certain you have been in your rebuttals of possible alternatives...

I think you might want to review what you think you know about the current state of dark matter research.

Tell me, where do you think the "fudge factor" is in this paper: https://arxiv.org/abs/1607.06218?
