"Diversity is valuable when it represents diversity of life experience and problem-solving methods, not when it represents some external characteristic like skin color or gender." First of all, gender is not exactly an "external characteristic". Secondly the life experiences of men and women are inherently diverse. Hopefully, someday the colour of your skin won't influence your life experience, but that is not the case in any human society that I am aware of.
