I'd prefer TheAmazingAtheists take on the situation.

He actually bothered to dig into the reports, the stats and his personal history/journal rather than simply look at the basics of "Wanted sex, killed for not getting it" and then turning that into a feminist movement. First he shared mutual hatred for both the women he didn't sleep with and the men who did get sex, he hated both men and women and wanted anyone who either refused what he wanted or had what we wanted to suffer. That's not sexism or misogyny, that's jealousy and envy. Even looking at the statistics of the shooting, 4 men died and 2 women. If twice the number of men die than women it's not exactly a case you can claim was sexist or against women. Hell, using stats like that is bad practice in general because it can highly be based on location. Such as what if he did it at his old boys only school? Then it would of been basically just men who died, but that would give us no grounds to say sexism against men. He could of done it at a store whose products tend to attract more than one sex than the other.

To determine if it was sexist we'd have to look at outside factors such as motivations, reasoning etc and info like that we do have all points towards jealousy and entitlement.
