Hmm.. What was this thread about again? The number of women invited to teach at a seminar. It has been noted that there are a lot more high ranked men than women in aikido. So, the ratio of men to women instructors would appear obvious. Im guessing that at the heart of this thread is the old " woman in a man's world" thing that many women must feel in life.
As a guy I'd just like to say that I like practicing with different people, and some of the women in my dojo are awesome, both to practice with and as teachers.
