Sunny, this was in response to Robs viewpoint concerning skill not being dependent on a practitioners fitness (which I believe was an offshoot of the male vs female at highest levels debate) rather than directly part of the on-going gender discussion. But to answer your questions
1. Do I equate women with frailty - nope
2. Do I equate women with less skill in aikido - nope
However, I do include a persons physical attributes with their ability to successfully defend themselves. Skill can help negate differences in body types and strength, but only to a degree which is set by the relative skill levels between the two people involved. I don't feel that any level of technical skill can help if your body is just plain not able to perform the necessary techniques.
However, for transmission of knowledge etc. I'd go with Ron's summation.
