maybe the real message is women saying: “We are scared of unknown men.”
It's not unknown men, it's alone with men, period. Most sexual assaults are not stranger-rapes; they're sexual assaults being committed by a person that was known to the victim. Often it's an intimate partner, a date, a close friend, or someone that they went to class/church/etc. with. If people you know aren't safe, then how could you trust strangers?
