Yeah... I tend to think it's a bit of an overreaction but I can also see the point that it softens the idea of what a monster like a rapist is thinking. I'm sure some of it is the dumb crap thinking she really wanted it but the idea it is the dominant reason for rape doesn't add up to me. Groping, or unwanted advances maybe but too many rapes are absolutely brutal and in no way do I think most rapists rationalize them in that way.
Well, yeah for sure. I guess to the victim it's all rape, but the offenders all have their various motivations. Every once in a while, I catch one of those shows my wife watches regarding the investigation and profiling of the criminal mind and I have to admit I do find it fascinating.
For some it may be dominance as you say. Others certainly just have trouble handling rejection, which is the type of creepy dude who gets my Ire up - I guess that's just because it's more commonly observed . Then there is always the person who's just a creepy perv, the socially awkward type who really just doesn't know how to go about achieving what he/she wants. And then there are the sociopaths who really just don't care and are seeking the most efficient path to what they want. The human mind is such a gray area, I mean you might consider the combination of broken aspects that contributed to Dahmer's atrocities.
Anyway, motivation for criminal behavior is an obvious tool for investigation, and in the context of the original comment it was anything but sexist.
I don't know Rath, and I'd almost expect that he'd come off as a douche that I wouldn't personally like, but I'm no fan the current vogue of trial by media where a person is guilty until proven innocent.
