I know that a lot of feminist fears about the trans movement have been, "Wait, we never got to the part where we focus on women! We tried for a minute, but we don't want to lose the category all of a sudden. We haven't heard yet from the females with children called mothers, we haven't heard yet from all these groups!" On the one hand I'm very sympathetic to that, but the category of Women or Mothers, any of these categories, are on shifting sands and always have been.
