I've deciphered the Voynich Manuscript. Here is the alphabet of the manuscript

[Michael Obraztsov]

It's difficult to understand how this basic fact consistently fails to spark any semblance of healthy self-doubt in many of the would-be translators.

Yes, in my opinion, healthy self-doubt is a basic prerequisite for making any meaningful contribution at all. You should also be able to discard an idea after thorough examination or present it for what it is: a spontaneous idea without any claim to correctness.

I agree. But the same applies to healthy research interest and healthy, open dialogue based on comprehensive analysis, which I have seen little of here.
