The problem is, we haven't evolved. Evolution doesn't work that quickly, not for a species with 20 - 30 years between generations. Instead we've civilized, that happens an awful lot quicker.
I'll agree with you 100% that it shouldn't be used as a defense, but I think not acknowledging it at all is just as dangerous.
The fact is that there's a reason that men commit the vast majority of sexual crimes. Part of that is simply because men are stronger, and strength is power, which has been codified over thousands of years into our patriarchal society. Which means that men have the ability to carry out these crimes, and a good likelyhood of getting away with them.
But a bigger part of it is that men at a very base level, feel that they should be having sex. They notice people they want to have sex with more, they fantasize it more. There's a lot of talk on the weight loss threads about "food noise", I'd like to propose the term "Sex noise" for what I'm talking about.
I don't think ignoring that that exists, and that its vastly more prominent for men is a good idea We've not evolved out of that, we've not had time. I think telling men that there's something wrong with them because they have that noise doesn't help. What young men should be being taught by other men is that yes, it exists, but that its something that you control, and that controlling it isn't difficult.
