Which brings me to the point that I know quite a few women who do actually watch (etc.) Doctor Who to a degree that I would consider fannish, but who don't get involved in organised fandom because they feel a bit excluded by the overwhelmingly male-centred character thereof.
I used to dress up as Leela, the Rani, Romana, Ace, even Zoe for conventions and Pledge Breaks. Unfortunately our local PBS station screwed our Dr. Who club, fired the club member who was on their staff for sticking up for the camera men during labour problems, and dropped the show. Meanwhile, a plethoria of other SF shows abounded, taking my attention away. Also, they cancelled the series, and not with a lot of Bangs, as with Blake's 7, but a whimper. The attempt to revive it on American TV gave us a Hollywood-drug-lord rendition of the Master. The lack of a decent villain was the nail in its coffin. But our Dr. Who fan club included lots of women and more straight males than gays, although there were certainly a few.
