I just don't agree that the gunman in Norway was insane. Disturbed maybe, but insane? He had clearly laid out and logical reasons for his attacks. You can read his blog. He was pissed off with the way Europe was being radically transformed by the left. His sentiments may have lead to extreme action, but a lot of people share them. Regionalization and globalization have a lot of people scared. Communities are changing rapidly, many beyond recognition within a single lifetime, at the behest of the agendas of governments and a select few globalist institutions. It just takes a few additional social conditions for particular people to crack and go on shooting rampages, i.e. radical ideologies.
I obviously don't support gunning down people as a way to solve problems. There are better ways. I do however support mass and violent protests, as well as revolutions where they are necessary to topple tyrannical regimes. What lies behind this situation is an angry and frustrated person who is acting out against the invisible walls that have been raised around him. He did it the wrong way. Now people will hate the right-wing and religious even more.
