Not discounting the excellent points made above, I can't help but feel that there are groups that have been fighting discrimination in institutions for decades and that maybe we need to work with them rather than reinvent a non-straight-white-male-wheel ourselves. People like http://womenintheartsfoundation.org/ , http://www.guerrillagirls.com/ , http://www.ifuw.org/ , etc. It seems to me like the kind of activity that WMF might have funds for.
