Drunk sex with consent does not constitute rape. It may constitute regrettable sex, but it is in no way the man’s fault for “taking advantage” of her. It is a choice to get drunk, so the things you do while drunk are your own fault. Waking up and realizing you had sex with someone you wouldn’t have while sober doesn’t make it “rape” and the man should not be punished for it. Obviously there are exceptions like if the girl was drugged or completely passed out, but if she is conscious and is able to speak and walk around like a normal drunk person at a party and gives a yes, that is consent, not rape.
