Gay Women make the best stage managers.
Followed by Gay Men.
Followed by Straight Women.
Followed by a floor lamp.
Then straight men.
(This is a joke I usually share with my staff)
I think that it will always be an individual who is a good stage manager, and not a sex or sexual orientation.
But if you speak in broad generalizations and sterotypes, the my joke holds true, in my opinion. BUT, that is based on my personal experiences - some of the best SMs I have worked with have been women - but there are a lot more women stage managing, thus, just plain odds would make it true that the best SMs I have worked with are women.
If you are going to play with broad generalizaions, then you are going to loose and offend.
and, what is the "best" sm? How do you compare?
