"What actions is the girl supposed to be held to? She was unconscious."

The question here isn't whether SHE could consent, because that was established.  The question is whether HE could.  His friends indicated that he was stumbling, barely coherent, and his recall of the night in question was clearly compromised.

Any fairly applied standard would allow for the possibility that BOTH parties couldn't consent. Either you're not a legal actor or you are a legal actor.  If the standard is applied one way for women, because they are presumed to be the one acted upon,  and another way for men, because they are presumed to be the actors, then it's a firmly subjective standard.

You can't compare a murder, where there's clearly a victim that died, to a sexual act where both parties typically mutually consent and there might not even BE a victim.  You cannot presume her victimhood OR his guilt.
