This
dichotic gender paradigm is harmful to the
mental health. and sometimes
physical health, of those that demonstrate that
male and
female are
insufficient as classifications.
Intersexuals are demonstrations that even the physical reality is that there are more than two sexes or genders. If you include the varying mental genders that are out there, it gets even fuzzier.
Or you can close your eyes and try and pretend there's only male and female.
