I think rape is a terrible crime, and certainly after 3, maybe 2, maybe the first conviction (with aggravating circumstances), there is a case for physical castration or other "more than prison" punishment. [But "date rape", which surely exists and is far too common, is also subject to the occasional false accusation.] Yet there is continuum of the total rape through date rape, through ignoring the "Don't do that", "Stop it"; "Don't", "Stop" >>> "Don't stop...". This last has already moved into the successful seduction realm, since the message has changed from no, to yes.

I'm afraid there is a BDSM continuum, too.
