At the Montreal seminar I asked, "Who is your nightmare opponent?" If you are a martial artist, take a few minutes and think about it.
One of the answers: "He'd be about 50% more than I weigh, much stronger with more skill and experience."
Yeah, that would suck, huh? Then add that he gets the first move at the time and place of his choosing. And he may be counting on a previous relationship with you to keep you from acting.
Gentlemen, our worst nightmare is where the average woman starts her day. We've been roughhousing, pushing and hitting each other since childhood and, largely, we've been encouraged. Sometimes overt, often subtle, girls have been punished when they wanted to play like that. So the average man reaches adulthood (even with no formal training) better trained and far more conditioned and experienced than almost any woman.
And men are stronger. We rarely get into contests of direct strength with women without holding back a lot, but when we do the difference is stark. (With the exception of KG and RM, two of my favorite cover officers.)
On top of it all, most women have only learned social strategies to deal with conflict...and social strategies not only fail but backfire when attempted on a predator.
Like I said, in LoV you come to this realization slowly and own it. Here it is quick and dirty. If you are teaching self-defense what you can do within your weight class doesn't mean anything. You need to teach people what works outmatched in strength, skill, experience and ferocity. How to deal when the assault is on before they are aware. And help them work out and overcome much of their social programming.
It can be done. It has been done. But not by staying in your comfort zone perspective.
