Will you take the pledge?

The AtlanticTLDR: Pledge to “boycott” (not speak at) panels you’re invited to, without first checking to confirm that the organizer has invited at least N>0 women (choose a value of N that suits how forgiving you’re personally willing to be; even with N=1 you will almost certainly decline a panel).
I hadn’t heard of this pledge before so technically didn’t “take the pledge” until just now, to myself. But I’ve walked this walk before, so to speak.
As far as I remember the brain was located in the head. So why would gender matter? If the person has something to say, they'd be on the panel.
This presupposes no bias on part of the panel organizer. Are you asserting no panel organizers exist who are biased against women? If one exists, there is a high probability that there also exists a woman with something to say on the subject of a panel organized by a biased person, and has been excluded on the basis of gender rather than brain.
Biases exist in every direction. For example, there are women only panels (often advertised as such). I do not believe that it is a significant enough problem, I don't think it should become an issue. Good ideas will win out in the end.
