And much like people can say 'no' and yet still be consenting.(Original post by Green_Pink)
The point is that even IF she said "Yes, okay" that doesn't necessarily constitute legal consent, in much the same way as a 15-year-old saying "Yes, okay" isn't consent either. If she was too drunk to be able to make a clear decision then it's rape. Considering she was very drunk, to the extent she can't remember anything and completely blacked out, it's reasonable to conclude she was too drunk to give informed consent.
The fact is that this case is unclear. The only way this could be confidently be said to be rape, without further details, is if we accept the idea that a man's penis comes with greater responsibility, which is obviously ridiculous and contrary to western ideals anyway.
To make another point, I don't think this debate should be about whether it was legally rape. To me this seems more a moral problem, as the OP isn't asking if she is entitled to prosecute him. And in this sense, there's almost no reason to believe that this is rape. Also I'd like to ask those claiming that a woman is incapable of rape how they feel about females who sexually abuse children.
Who do you think it is...
