That most women are assaulted by someone they know is a fact I'm personally familiar with unfortunately.
Here's my thought on why I like the idea of this kind of seminar:
1) Men get in fights, but more times than not it's a liquor-induced bar fight. I'm NOT saying guys don't have to fight for their lives at one point or another ~ it all depends on the situation naturally. But the guys I know have had to deal with bar fights, parking lot fights and (rarely) muggings.
As you know, rape is very different. I obviously don't have to go into graphic details here, but rape certainly presents specific issues. I want those exact scenarios played out in my training so I can learn them and work on them. I love Krav and will continue to train, but I don't get nor do I expect my classes to be emphasized in this way. I learn to punch, elbow and kick ~ that's very cool. But if my instructor offered a specific class or two on how girls can fight against a guy specifically (especially if she's pinned, and there's almost always a huge weight difference), I'd be thrilled.
I'm sure our instructor will touch on that at one point in class, but it's been 2 months, and I haven't seen it yet.
2) Most women I know would never so much as walk into a Krav Maga class. They think it's over-the-top, testosterone driven guy stuff, and they're totally turned off. They're even less likely to stomach a grappling lesson. But they WILL take an all-girl rape prevention course (even if it's the same stuff offered in Krav) simply because it's a less threatening environment. I know it's silly, but I understand the emotion behind it.
As for the stuff on Rape Escape's website, some of it does sound scary. But again, most women I know don't think twice about this stuff. It's the kind of thing that happens to someone else, not them. Example: When I told my mother I was taking Krav, her exact response was, "I don't know any of that stuff, and I've been fine all these years." Both she and my father think I'm ridiculous.

My sisters, cousins and nieces won't come to *any* of this stuff (not even the all-girl IMPACT course). They think it's a waste of time. Go figure, eh?
Ah well. I'll let you guys know if it was worth the time and money.
