Not to be too doctrinaire, but we live in the patriarchy! And therefore anything explicitly associated with the female gender, including motherhood, needs to be defensively claimed, because it's either devalued or sentimentally idealized, but not supported. I so thoroughly believe that female human beings have worth that I don't feel the need to argue it, but I think that there's a part of me that very specifically wants to make space for those ideas to be centralized, if only for the moment.
