As I’m sure you’re aware, many women are shamed into hiding the fact that they were sexually assaulted. It is extremely common for the woman to either blame herself, or feel disgusting, or to be afraid of not being believed or of the police themselves. A lot of women in these categories do not report their rapes. Only about 30% of rapes are ever reported. Many women feel they need to just move past it, and many are told that explicitly.
But when you see your rapist reaching a powerful and influential political office, like the mayor of New York or the president of the United States, you might feel compelled to finally come out and say something.
