 Dembroff’s understanding of critical and non-critical gender kinds importantly makes gender kind membership something more and other than a mere psychological phenomenon. To engage in collectively destabilising or restabilising dominant gender normativity and ideology, we need more than mere attitudes or mental states – resisting or maintaining such normativity requires action as well. In so doing, Dembroff puts their position forward as an alternative to two existing internalist positions about gender. First, to Jennifer McKitrick’s (2015) view whereby gender is dispositional: in a context where someone is disposed to behave in ways that would be taken by others to be indicative of (e.g.) womanhood, the person has a woman’s gender identity. Second, to Jenkin’s (2016, 2018) position that takes an individual’s gender identity to be dependent on which gender-specific norms the person experiences as being relevant to them. On this view, someone is a woman if the person experiences norms associated with women to be relevant to the person in the particular social context that they are in. Neither of these positions well-captures non-binary identities, Dembroff argues, which motivates the account of genderqueer identities as critical gender kinds.
