What women are really doing with this "No means no!" campaign has not
so much to do with stopping rapists as it has to do with pushing
responsibility onto men's shoulders, something that's hardly new.
What "No means no!" really means is this:
"We women understand that much of what we say is ambiguous. We
understand that we sometimes say 'Yes' when we mean 'No' and vice
versa. We understand that you men, and in fact other women, have to
read our body language, listen to our tone of voice, and use other
clues to determine what we really mean when we talk. We understand that
misunderstandings are common. However, we refuse to take any
responsibility for this. If, in the future, there is any
misunderstanding between us, if there is any misinterpretation of what
I said or what you said, then we want it to be your fault. Regardless
of how vague we are, it's your job as men to figure out what we meant
and act accordingly, even when we don't know ourselves what we meant
until we reflect upon it later."
