They were all men. Beyond that, most of them felt they were somehow being denied something that they should have been given. That attitude didn't appear out of thin air. It was honed by our culture, generation after generation, perpetuating bad ideas and stereotypes over time. Elliot Rodger is just the latest permutation of the guy who thinks that he is owed something and demands retribution. Rather than figure out that maybe he might not be communicating with women properly, he blamed their lack of interest on them.The vast majority of men aren't evil, though. It does us no good to vilify an entire gender. But our culture that perpetuates this attitude among a small minority of men needs to be scrutinized — so all men and women can feel safe to speak the truth.
