This isn’t the first article to make this point, but it’s very detailed and well-written:
The man who shot nine people to death last weekend in Dayton, Ohio, seethed at female classmates and threatened them with violence.
The man who massacred 49 people in an Orlando nightclub in 2016 beat his wife while she was pregnant, she told authorities.
The man who killed 26 people in a church in Sutherland Springs, Tex., in 2017 had been convicted of domestic violence. His ex-wife said he once told her that he could bury her body where no one would ever find it.
The motivations of men who commit mass shootings are often muddled, complex or unknown. But one common thread that connects many of them — other than access to powerful firearms — is a history of hating women, assaulting wives, girlfriends and female family members, or sharing misogynistic views online, researchers say.
