E.R. Campbell said:Blowing off steam in online fora like Army.ca is pretty harmless, but blowing off highly partisan steam in public, in print, draws some attention if one is either of both a) an extreme partisan blowhard, and/or b) not a very good writer. See the reviews (at the bottom of the page) of this book, for example.
While I have not read the book, from some of the media attention surrounding it, it seems to be quite well-researched from a non-partisan, academic perspective. A Google search reveals that one of the commenters, Justin Arjoon, is an NDP riding association President and was a campaign manager for the same party; an NDPer calling a Conservative biased isn't exactly new or surprising :blotto:
