Facebook pages and Twitter feeds filled with comments and multiplying threads from women who recalled being groped by doctors, by piano teachers, by photography instructors, by perfect strangers. They told stories of being flashed on the bus by masturbators, of having male colleagues rub up against them at the copy machine in their office, of dates and bosses demanding sex.

Sasha Stone, an entertainment journalist, told of being forced to perform oral sex on a man “after he offered me a ride home and then threatened me. I was 14.”

Wendy Luxenburg, 45, a hospital administrator in Chicago, recalled being in a Florida department store with her mother: “She was an aisle away. Man walks by me, rubbed by crotch. I was 11.”

And the actress Amber Tamblyn wrote on Instagram of being accosted at a nightclub by an ex-boyfriend who grabbed her by the hair and, with his other hand, lifted her by her vagina, bruising her badly, and “carried me, like something he owned, like a piece of trash, out of the club.”
