I think for a large amount of people the "sober" part might be difficult. My college said consent was "sober, verbal 'yes'". Yeah, that sober part tripped up a lot of people. I also think a lot of people can twist that, though, and point at situations where both people have been drinking and say, well, if they're both drinking the person who says they were assaulted or raped might be on the wrong end themselves. (A friend had that happen to her.)

Yeah, I agree we need to shame the rapist. Though I think for some of them it's not so much of wanting to find a consenting partner and never being able to, for some of them it's the pain and power they look for. But I suppose serial rapists might have a slightly different pathology from date-rapists. I don't know... Haven't read much primary research about rapists.
