Extremisms of any kind that lead this kind of bombing and killings is worse than terrible not sure why some brings the muslims into this particular tragedy at Utoya and Oslo it seems the right wing terrorists are as deadly as can be and can singularly inflict enormous damage. It seems both the communists and the ultra right wing have both been behind the worst acts and worst systems (Communism in Eastern Europe and fascism in Germany, Italy and Spain) we have seen in Europe, the extreme Muslims seem to have made far less damage in Europe so far. Lets hope we can avoid more of these terrorist acts by violent "idealist" and madmen...but I am not sure how.
