Don’t misunderstand me; when I said it was “well-written,” I did not mean that it wasn’t pretentious and overblown, but that it was grammatical, with proper spelling and punctuation, and that she seemed to have a decent vocabulary.
Okay: By that standard, "Mein Kampf" was likewise "well written."
Pace, Steve_Seattle!
Besides, I wouldn't be surprised if she used a commercial app to check the grammar. As for the vocabulary: A good thesaurus can be used to fake that (though the result will end up seeming "pretentious" and "overblown").
Her rant is one extended metaphor, and really tries one's patience reading it!
