I don't understand your point. It goes both ways; most men would have a problem being forcefully harassed by an unattractive woman, and perhaps not when by an attractive one.
Her point is that she's being harassed by someone she does not want to be harassed by. Don't turn this into a bitter "you don't give unattractive men a chance" argument. The same concept applies with men towards women.
I'm sorry, but I don't see how a man "grinding his crotch up against your leg" can be considered a "hit on" a woman. I think you're arguing about something else entirely.
