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.
