If male dominance in the dojo creates a barrier that keeps women out of the dojo, then by your own argument, something should change. So what can change? Well, someone creating an all-women dojo is one way.
It can change, but is it the best change to accomplish your goal?
My parents grew up in a south where seperate was considered equal. Please note that this did not function as a "feeder system" in any way. I've gotta go with Chris and Asim here. In general, I'd have to question this way of bringing in more female students.
