He didn't have asperger's. He had a sense of privilege and didn't like that it was challenged. This isn't the first example of this. Marc Lepine highlighted this kind of behaviour years ago:
http://en.wikipedia.org/wiki/%C3%89c...nique_massacre The Montreal Massacre (a date I never forget and one that just highlights how horrible some men are in regards to their views of women) was one of the first searing examples of hatred towards women that society has an undercurrent for.
What's really horrible is that we see this again and again and yet.. do little, if anything, to address that sense of privilege. Losing one's privilege is not emasculating or horrible or anything. It's creating a society where everyone has a say and belongs. We really need to stop, IMO, spending so much time on sympathy for the killer and spend more time on what was lost, those women who could have changed the world in so many ways.
