of course you are correct, but I was drawing attention to the fact that if more women were put off aikido by rolling than men (or vice versa), they would not be responding because they would no longer be doing aikido and the women (and men) who stay tend not to be put off by rolling.
I was also intrigued by more men having done another martial art. It's true I've never seen a dojo with more women than men in it, in any martial art.
(this does not infer I'd like to force a 50:50 balance! People can make their own minds up.)
I'm wondering, in dojo's with a female sensei, are their more women than men (or at least is the ratio higher?).
