I just read this post.
Definitely an angry response, but not necessarily by a "stalker" in the sense of someone bent on violence against Chaim.
The viewpoint expressed is the same as that of Olmert when he debated Rabbi Kahane, and ridiculed the Rabbi's convictions that Jews must fight back and drive out the Terrorist Arabs. Olmert smirked and insisted that Kahane's way was the "reason" for terror rather than the way to end it.
Even so, the words of choice by this poster are chock full of militant imagery, so caution should be used. The aggressive manner projected strikes me as coming from an Israeli in the IDF whose complete allegiance is to his government and the status quo.
