As V (of “V for Vendetta”) said, “You cannot kill an idea. Just a point of view.”
The idea of Canada–a modern, progressive, Rule-of-Law-governed, and economically-sound state–will not die, no matter what. I subscribe to it, as you likely do too. So, it appears, do many of the contributors to this thread.
If the gunman had made it into the Commons chamber and started shooting, would that be the end of Canada? No. As stated, you cannot kill an idea–we would mourn, but we would put new members in that chamber and carry on.
But the point-of-view of the attacker can be killed. We need to let people with such views know that what their so-called idols do is barbaric, is done in the name of power (not religion), and that they will not be honored for joining the fight; but rather, be cannon-fodder on the front lines, so those more ideologically-pure (and most assuredly non-Canadian) will be safe.
Do we need to build “Fort Parliament,” as a previous poster alluded to? No, I don’t think so. One of the great things about our country’s governance is its transparency. The fact that an ordinary guy like me can visit our capital and sit in the public gallery of the Commons and watch our government make decisions is a cornerstone of our democracy. I would not want to find that our government could only operate in camera, sub rosa, and so on; because the public is too dangerous to let into the decision-making chamber. That is truly scary; as, if that comes to pass, we might as well be the USSR, North Korea, Cuba, and other such bastions of personal freedom.
Shamozzle, you have said, repeatedly, that we need to “do something”; now and in the future. What, precisely, do you think we should do?
