I can't see how misogyny can possibly be so easily dismissed as you have done here. Have you seen the sites he was part of, and what they believe about women? Here is one MSM link to get you started:

His posts to PUA hate reek with hatred for women. And why are they there? Because the PUA hate site -while disagreeing with the methods that the so-called "pick up artist" community uses- shares the same beliefs as PUAs about women. Inferior, irrational, prefer authoritative men who tell them what to do and take charge over them; worth lies only in looks and reproductive ability (as compared with a man's worth, which lies in intellect, personality, and achievement). Many posters urge tactics which would be considered rape (get her drunk, ignore the "no", etc).
I really urge people to look into these groups. PUAs, incels, so-called Red Pill Men, etc. I believe it was RooshV, the founder or at least biggest voice for PUAs who posted a piece yesterday saying basically that if men continue to be sexually frustrated by women then more violence like this will happen.
And crap like this has a BIG audience of men. And not just mentally ill men, as ER may or may not have been. We need, as women, to be aware that these guys are out there, and what they think about us, and what they plan for their interactions with us and our daughters.
So don't tell me misogyny has nothing to do with it. It has everything to do with it. This guy's disgusting beliefs about women were right at home among a certain segment of American male population.
