Rapists target people who are vulnerable to establish power and control. It's a dehumanization and violent urge primarily motivated property rights and entitlement mentality.
It is not a subset of sex. This is why it's called sexual violence and not violent sex. Rape assumed from attractiveness and desirability and cultural norms of beauty standards perpetuates myths about the crime that is unhelpful, patronizing, paternalistic, and counter-productive.
Gang rape, stranger rape, acquaintance rape, date rape, statutory rape, child rape, marital rape, intimate partner sexual violence...all fall under the same generalized umbrella of entitlement mentality and dehumanization.
This is what the world needs to fight against. Not some inane and lousy guesses about how women need to take responsibility for avoiding getting raped by rapey men.
