I will remind you of this section of the article: “If you’re wondering why she flinches when you walk past her at less than a metre’s distance, take a second to think about every time you’ve seen sexual harassment happen around you and you’ve not taken it upon yourself to say anything against it.”
Choose to educate other men who you know to be guilty of harassment and to call them out when they engage in threatening or imposing behaviour. As I was discussing with a friend recently, it’s not just women who suffer as a result of this; like the passage above says, when a women is made to feel uncomfortable by men on numerous accounts she will assume that this behaviour could come from any man. Nothing will change if women are the only ones speaking up about it, men need to join in the conversation as well.
