The problem with many of the modern fake theories is that those who believe in them are often like those who believe in New World theories (or most other theories). They cherry-pick examples of similar imagery from modern sources and ignore similar imagery from medieval sources. Or they cherry-pick New World imagery and ignore similar imagery from Old World sources. These are examples of self-validation.
The problem with most of the text-related theories is their proponents have not really studied the structure of the VMS text. Torsten, at least, has made an effort to try to figure out how the tokens are constructed and how they are inter-related. This is rare among Voynich text theories. Even if it's not a perfect description of how the text is generated, it's more productive and revealing than those who try to force the text into words by starting with a substitution cipher and then subjectively rearranging everything to try to make it meaningful.
