If it wasn’t attributed to someone specifically, it would be just dismissed as the ravings of a lunatic, like those wackos who yell random phrases on the streetcorners.

You will find that most LDS know nothing of these doctrines. I have asked regular members about them many times, and not once did they know what I was talking about. Sure they are part of LDS Doctrine, but I suspect they are rarely, if ever, taught in church. It is the social aspects of the LDS faith that draws and keeps people.
