Stephen Harper is a VERY sick man. His hatred of the Liberals or anyone who is not in absolute, total agreement with him is what drives him - to the point where he has now crossed the line & is showing his insanity.
There is a lengthy post I bookmarked about a year ago on Harper that has a deep psychological profile on him titled: The Singular Face of Megalomania
by "the Ball". It's a long read but well worth taking the time.
I also found this article titled "Profile of the Sociopath" which is applicable to Harper. There's a lot there that fits him to a T.
Being Sunday & generally a quieter day, although these days seem to be more hectic than usual for obvious reasons, I hope you can find some time to read these excellent, insightful articles.
