So let's just all say this together: Women should never be sexually assaulted AND an accuser's sex life is irrelevant and should not be a factor in ascertaining whether or not an assault happened.
I think that this is something uncontroversial that all of us, regardless of political stance, can agree on. If you don't agree . . . well then you have an extreme position that I'm not really interested in arguing about.
OK. Good. Now, then, why is an accused's drinking habits or propensity to drink to forgetfulness relevant as to whether or not he committed sexual assault? You may respond, "it's not, it's relevant to whether or not he would remember sexually assaulting someone" But this is just kicking the can down a bit, begging the question, really. Shouldn't there be evidence pointing to a sexual assault occurring in the first place?
I think there should be some evidence before we start thinking someone might have sexually assaulted someone else. If drinking habits are not relevant to ascertaining guilt, then they only serve as a way to smear the accused -just as sexual habits are used to smear the accuser.
