Do they have an extra bone in their vagina that allows this to be so? How is this claim substantially different from the famous Nick the Greek (I think that was him) blunder when he said African Americans made better runners because of their genetics. Do you believe it is genetics? Hormonal? Or is this just based on your feelings (professional, not trying to imply anything) for a student who happens to be female?
I have been teaching magic for well over 20 years. I have seen how boys/girls/men/women learn and perform. Here is what I have observed:
As a rule, females are more careful technicians than men. They spend more time focused on the elegance of the technique and perfection of the move. They tend to learn quicker as they are more willing to observe the model and attempt to replicate it.
Men, on the other hand, seem more easily able to stand up and bluff their way through a routine, letting personality and chutzpah cover technique. They more eagerly want to "get their hands on things" rather than observe, analyze, and apply.
Have their been exceptions to these observations? DEFINITELY!!!
But, I have worked with THOUSANDS of students. This is what they have taught me. When I work with a group of all male students, it is a different approach from when I work with all female. When I watch them perform, there are often different approaches in their manner of interaction - the men more "performing" the females, often, "sharing." I have seen these qualities in both genders, but overall I would tend to characterize the "sharing" dynamic as slightly more of a female trait.
But ultimately, the personality of the student is the greatest determinant of their success or failure. While I may see trends in gender populations, I have never seen anything exhibited consistently and exclusively from one gender over the other that would indicate the potential of any superiority in the magic arts.
To say that women can be superior based on the fact they have a vagina seems to me to either be an oversimplification or just plain wrong.
Now, if you want to couch the argument in terms of qualities other than gender, we might be able to agree. But we would have to acknowledge then that gender - which is the basis of your assertion - plays no part.
If it did, then the most famous magicians in history would be female, no? If it did, then the quality of performances by female magicians would consistently be better than that of any of their male counterparts. Or does that open up the issue of oppression by the patriarchal authority?
