No Mike, you would need to be encouraged by what encourages you. Her point is that what encourages you might not encourage beginner female aikido students and they should get to be encouraged AS WELL.
All, Paulina and Mary made this same valid point as this person. (IMO) Namely, that the more women they see, especially in the upper end, the more encouraged the new (and not-so-new) female aikido students will be. While it is certainly a valid point, I don't think it is so valid that we should try to make the Aiki Expo equitable by inviting people with less ability than the 33 men who accepted the invitations.
If there were an all female sensei aikido seminar anywhere near me, I'd go. However, and let's be honest, if they were all 5th and 6th degree black belts and it happend to be at the same time Endo sensei (at 8th degree black belt) was doing a seminar about the same distance away - I'd go see the more senior instructor. Wouldn't you?
Here is another idea. I agree that women instructors should get more exposure. What if someone started a non-profit that people donated to, which could be used exclusively to defray the cost of flying in and paying senior female instuctors for doing seminars? Does the "passion" for this cause t extend all the way to the checkbook?
