I think we have to discuss what made him do this we have to understand so we can try to prevent (as far as possible) others from having the same distorted thoughts as this guy. And we have to understand so we can discredit his manifesto. In short we have to discuss him into irrelevance.
One of the posts on this thread alluded to the blame being put on mothers. In this case a mother who raised her son on her own (father not really in the picture much then not at all in this case - whether that is relevant or not I don't know but those are facts anyway) and may be seen as having "failed" in her job of raising him.
As a more encouraging story showing that she may not at all be vilified in Norway (whether she is abroad or not) may I draw your attention to the following Facebook page which was set up in support of Breiviks mother www.facebook.com/event.php?eid=133878510033038 yesterday. It got over 10 000 members in a few hours.
The text in the "more info" part, translated by me, says:
Dear Mother Behring,
In these devastating time, for you, and the rest of the nation, we in this support group would like you to know that we are thinking of you, you are also one of the bereaved. You have also been cruely effected, you are also one of the victims, you are also one of them who shall be met with more compassion, more love and more thoughts.
One of the entries on the wall says "from one mother to another mother" and signed with a heart.
I think that facebook page says a lot of the true nature of Norwegains, both men and women.
Why not show your support as feminists by becoming a member of this facebook group. The bigger it becomes the more clearly we can all make a stand against blame being placed on mothers.
PS: to Sakura's comments about handing him over to the mothers who have been bereaved of their dc's, what good will that do? That will only serve to demean their grief and would not exactly be in keeping with the values their children clearly stood for - democracy, human rights and the rule of law. Besides violence never discourages violence (otherwise the US would not have any murders in states where they execute surely).
