Statement: IF Voynichese does not represent natural language...

[nickpelling]

With "deceptive" I mean that efforts have been made to make it look like something it's not. 

For what it's worth, one related argument I've put forward for some years relates to the Voynichese glyphs 'o' and 'a': which is that even if you put everything else about Voynichese to one side, 'o' and 'a' simply do not behave in a language-like way. From this, I conclude that they are not 'undeceptive' vowels, but are instead artificial constructs performing some other function entirely (e.g. they are verbose ciphertext shapes that need to be parsed as a pair to make sense).

Labelese makes this artificiality particularly visible, but the sequential repeats of 'or' (e.g. on folio 15?) are much the same. And so forth.

And if 'o' and 'a' are "deceptive", then so must the rest of Voynichese be (to a large degree, at any rate).
