I don't know of a better description than this: what is being taught about Cumorah are the philosophies of men, mingled with scripture.
The Book of Mormon itself warns us of this danger.
O the vainness, and the frailties, and the foolishness of men! When they are learned they think they are wise, and they hearken not unto the counsel of God, for they set it aside, supposing they know of themselves, wherefore, their wisdom is foolishness and it profiteth them not... But to be learned is good if they hearken unto the counsels of God. (2 Nephi 9:28-29).
The entire premise of M2C (Mesoamerican/two-Cumorahs theory) consists of setting aside the teachings of the prophets and apostles about the New York Cumorah, supposing they know of themselves.
The M2C intellectuals think they are wise--wiser than the prophets and apostles. They have persuaded their students for decades that they (the intellectuals) are wise, while the prophets and apostles are naive speculators who misled the Church about Cumorah being in New York.
Now those trusting students themselves have become teachers at BYU/CES, historians, Church employees who set up the displays in the Visitors Centers, etc.
Instead, their confirmation bias is so strong that they honestly believe they are not setting aside the teachings of the prophets because, according to them, the prophets never taught that Cumorah was in New York.
Of course, that's walking in darkness at noon day. Letter VII and all the confirming teachings of the prophets and apostles are as plain as word can be. Yet, the intellectuals are imposing their falsehoods on the entire Church through their journals and publications, the Visitors Centers, the curriculum, the media, etc.
To confirm their M2C bias, they have invented a Church history narrative that not only is unsupported by historical documents and accounts, but outright contradicts them. This imaginary Church history is being taught at the North Visitors Center on Temple Square, as discussed here:
It's one thing for the Visitors Center on Temple Square in Salt Lake City to mislead people about what happened far away in New York, but they have replicated this exhibit in the Visitors Center at the Hill Cumorah in New York!

Nothing in the Cumorah Visitors Center tells visitors (or missionaries) what the prophets and apostles have taught about that sacred location, apart from Moroni's stone box. Instead, the exhibits and artwork teach M2C.
Visitors are never taught about Mormon's depository or the final battles of the Jaredites and the Nephites.
This display of the "New York hill" (they refuse to call it Cumorah) shows Moroni burying the plates, along with the Liahona and the sword of Laban.
It's absurd on many levels. First, Joseph and Oliver each described the contents of Moroni's stone box in detail: plates, breastplate and interpreters. No one ever said the stone box contained the Liahona and/or the sword of Laban.
This exhibit is pure fiction.
The exhibit is accompanied by a film that actually depicts Moroni putting the Liahona and the sword of Laban into the stone box.
We're supposed to believe that Joseph either (i) carried these objects home, and then to Harmony, and then to Fayette, all without anyone else ever seeing or commenting about them; or (ii) left them in the stone box for several years, where all the people looking for treasure never found them.
Neither scenario is plausible, to say the least.
We all wonder, "Why would Church historians and media employees create this false narrative?"
The answer: M2C.
If the Visitors Center displays depicted the words of the prophets instead of the words of the intellectuals, we'd see Mormon's depository (Mormon 6:6) and Moroni's stone box in the same hill. This is what Joseph, Oliver, and all of their contemporaries and successors have taught.
It would look something such as this:
