Before the assault, Ms. Logan said, she did not know about the levels of harassment and abuse that women in Egypt and other countries regularly experienced. “I would have paid more attention to it if I had had any sense of it,” she said. “When women are harassed and subjected to this in society, they’re denied an equal place in that society. Public spaces don’t belong to them. Men control it. It reaffirms the oppressive role of men in the society.”
