In case you doubt patriarchy is lethal, see recent Nextdoor "conversation":
CC: Man shot and killed another man who slept with his wife. The cheating wife was unharmed.
JAS: Well it looks like the wife should have been harmed just saying... she started it all LOL
and
AK: Well, you sleep with another man's wife, your life is officially forfeit.
Etc.
FWIW, "JAS" is a woman advocating for male violence against another woman. I can't even.
