BTW, by "assuming girls are upset where they'd assume boys are angry" I am referring to unconscious fact judgements about infants too young to verbalize the problem. (Cite: "pink brain blue brain" by Lise Eliot). Macho emotions are attributed to babies in who appear male and gentle ones to babies who appear female. Since baby sex is almost unmarked, that means going by the colour of the clothes. (And google "baby Storm" for an example of adults panicking and pillorying the parents if the cues that allow them to gender the baby are intentionally witheld.)
