Really? He was motivated by mysogyny, if I remember correctly. So please point out to me (1) spiritual advisors he sought out (and who responded) to answer questions on when it’s appropriate to shoot women; (2) mysogynist organizations he supported financially, (3) policy changes he was pressing for (at risk to his career) for the sake of mysogyny, and (4) a well known and deadly mysogynist organization based in a foreign country that applauded his actions.
I think some of the dogged obtuseness not to see an easily foreseeable threat, call it “terrorism” or what have you, because we’re afraid of seeming insensitive – is in large part what allowed this mass murder to happen.
