> There doesn’t seem to be any good definition of what constitutes either gender

Gender can refer to two different things:

“Ascribed gender”: what bucket (or buckets) of the set labelled “genders” by society does society at large (or, in certain contexts, some defined subset of society other than you yourself) put you in.

“Gender identity”: what bucket (or buckets) of the set labelled “gender” do you yourself feel you belong in.

There is no objective set of traits defining boundaries of gender buckets, no objectively correct number of gender buckets, and no objective need for their to be any set of buckets labelled “gender”. It is all path-dependent social construction that varies by social context and individual.

(“race“ works the same way as “gender” here.)

Does race work the same as gender here? I get that it's often still very arbitrary, but it's certainly less fluid (or rather, fluidity in this area is less acceptable). I can't love Mexican food, learn Spanish, and then decide that I identify as Hispanic. Inversely, if I found that I enjoyed wearing women's clothing and partaking in feminine activities then I could identify as a woman if it suited me.

In the sense that “‘race’ can be substituted for ‘gender’ without loss of accuracy in the description in GP”, not “the dynamics of the degree of social acceptance of divergence between ascribed race and racial identity are identical to those for gender.”
