If I organised a conference, and failed to attract a single female speaker, especially in a community where sexism is a sensitive issue, I would immediately decide to cancel it of my own volition. I don't want to contribute to the type of things that make women feel excluded.

So if women choose not to be included on your activity, you would cancel it, because women would feel excluded? OK....

If I never took part in anything that didn't attract females (that were not family), I would have never learned anything, or seen any movies, or eaten any food...

That's a bit of a disingenuous comparison. Organizing a conference that should be representative of a very large, diverse community is not quite the same as organizing personal activities.
