One can do many things to a manifest truth. One can deny it, defame it, defang it, derail it, degrade it, deride it or destabilize it. But one cannot "debunk" it. That is because the truth is not "bunk". Try as one might, whether sincerely or not, one cannot "debunk" what is not "bunk" to begin with.

One cannot deoxygenate hydrogen (as far as I know) and no effort to do so, however well intentioned, can be described as deoxygenation.
