I think the phrase you quote, though, is a quote from the book.

Ah. I was confused by the lack of quotation marks.

You don't find it in any way problematic to use a loaded phrase like that, especially when likening the situation to an exchange in committee e-mail? On the face of it, it sure looks like a negative imputation is intended.

As for borrowing the book, thanks, but I think I'll pass. As quoted, the author sounds patronizing and prescriptivist.
