my theory. which is mine.

You might have seen the PBS look at fan art which didn't see any women to talk to.

And this comment on the erasure of female fandom.

And now I am going to tell you my theory, which is mine, which is: Some men know that women aren't funny. They may not say so, maybe not even to themselves, but when they perceive a woman being funny they experience cognitive dissonance, and need to find some other explanation.

I ran into that a lot on Usenet, where I would say something funny and then some guy would explain to me that what I said was funny. And I always wondered, what did that guy think I was telling that story for, if I didn't know it was funny?

At this past Wiscon, ljgeoff said that she thought she was turning into her grandmother, and amaebi said, "I do hope she's not dead." Some guy who overheard this chortled about inadvertently funny things people say at Wiscon. Okay, people do say inadvertently funny things all the time, but why would that be your first interpretation? If amaebi didn't mean to be funny, what did she mean?

And the fan artist in the PBS video who can't understand the artists in BBC Sherlock fandom, are they joking, what the heck is their deal? He mentioned this piece, which depicts Sherlock as an alpaca and John as a Corgi (yes! he is such a Corgi!). He's thought about it enough to talk about it on TV, and he can't tell whether it's supposed to be funny? Really? Really??
