Unraveling the Voynich Codex

[Anton]

Anton, what you say is right, but criticism coming from fellow academics tends to be phrased in certain ways, and what has come from the internet Voynich community certainly includes a fair amount of hostility.

Talk in the internet can be notably harsh in general, this is an interesting phenomenon (and I'm certain it's being investigated and somehow explained by science), but it's not specific just to "Voynich" internet community in particular. They do not contrapose "hostility" of the internet to "friendliness" of academics. Instead, with this phrase, they implicitly substitute "hostility" for "profanity" and it is opposition of "enlightenment" of academia to "profanity" of the internet that blatantly rings here.
