If you are accused of raping a girl on the sole grounds that she was drunk when you had sex, then the fact that you were also drunk should be grounds for a counterclaim of rape against her.

Obviously, that would be ridiculous. But so far as I have read, only Brown's policy explicitly takes the position you advocate, that while the female being drunk casts blame on the male, the male being drunk casts even more blame on the male. ("A charged student’s use of any drug, including alcohol, judged to be related to an offense will be considered an exacerbating rather than a mitigating circumstance.")
