Let's try this again:
The common denominator of sexual assault is not the behavior of the victim. Sexual assault happens when the victim was at a big party, a small party, a party with alcohol, and a party without alcohol. People are sexually assaulted on their way to work, at work, and coming home from work. Sexual assault happens to children, adults, and the elderly of every ethnicity and religion to every time of day and season of the year by people they know and don't know.
The common denominator of sexual assault is the perpetrator, a person who puts their pleasure above another person's basic human rights of health and safety. We will never end sexual assault by holding victims accountable and giving potential victims the illusion of safety if they avoid certain behaviors. Ending sexual assault will only happen when the emphasis is on changing the behavior of potential perpetrators through learning about consent and the consequences of their actions. They are the only ones who can stop it. And we are the only ones who can stop them.
And by the way: #metoo
Move with intention.
