Full Idea
In a rape a person is used without proper regard for her personhood - but this is true of every kind of assault.
Gist of Idea
A rape disregards the status of being a person - but so does all assault

A Reaction
This is a good step towards her attempt to pin down what is specifically wrong with rape, which strikes me as an extremely important question, and not merely in order to justify punishments.
