THE NORWEGIAN PARADOX

I don't get this one at all.  A radical Muslim hates Americans and Europeans so he kills Americans and Europeans.   A radical guy from Norway hates Muslims but, kills Norwegians?  Don't get me wrong I'm not in favor of murdering anyone, anywhere at anytime but, I am a big fan of logic.  This is not logical.  If you have been paying attention to this nut, you will also find out that the Justice System in Norway is also nuts. 
This guy is allowed a one hour soapbox to disseminate his nuttiness and the prosecutors shake his hand.  Apparently his may get 21 years in prison for killing 77 people, including many children.  TWENTY-ONE YEARS!  WOW!  That's less than six months per person...WTF???
