Rodger left behind a manifesto. It details the thoughts of a young man who was filled with hate and rage because he wasn't in a relationship; there is also much evidence of extreme narcissism..
I was interested in how those on the left might see such a crime and found a piece by the feminist Jessica Valenti at The Guardian. She highlights the fact that Rodger was a misogynist - which he most certainly was. But she then tries to tie this into a left-liberal world view in which all evil is supposed to flow from white males as a privileged oppressor class.
As far as the race angle goes, she writes:
Yet, as the artist Molly Crabapple pointed out on Twitter: "White terrorism is always blamed on guns, mental health – never poisonous ideology."
She is arguing that Rodger carried out an act of "white terrorism" inspired by a "poisonous ideology".
Now, that's an odd claim as it's more accurate to put things the other way round. Rodger was of mixed race, with a white father and an Asian mother. And he made clear his hatred of blonde women ("I will slaughter every single blonde s*** I see"). So the truth is that a mixed race man set out to attack white women - how can this be described as an act of "white terrorism"?
And then there's the gender angle. Valenti writes:
The truth is that there is no such thing as a lone misogynist – they are created by our culture, and by communities that tells them that their hatred is both commonplace and justified.
It's that feminist idea that the average man hates women and that the culture supports them in this. As it happens, Rodger in his manifesto is perplexed that the other men he befriends, who also haven't been able to form relationships, aren't angry and hateful like he is but choose instead to pursue their strengths. The reality is that he did, indeed, end up as a lone misogynist.
One of the patterns of these types of crimes is that they tend to be committed not (as the leftist theory might expect) by masculine and traditional white males, but instead by socially maladjusted, loner young men, who feel themselves to be outsiders to a system they feel alienated from.
