How does “being able to handle yourself” apply when someone else has removed your ability to handle yourself with drugs or alcohol? How does it apply when your choices are “go along with it and try to escape later” or “fight back and probably lose because you have less muscle mass and are physically smaller than them”?
How does your argument apply when you are a teenage girl in high school being harassed by adult men? Reality is a very different place when the world perceives you as a woman (or girl), and your prescriptivist approach entirely fails to account for the fact that your perspective has a lot of blind spots in it.
