Oh, collective consciousness isn't a gender, but drinking beer and watching sports is? Or maybe we'll go to the biological essentialists and ask if a set of chromosomes is a gender. Or we could look at modern feminist theory and check whether performing for the patriarchy is a gender. Or we could go to the evolutionary anthropologists and ask if the social conditions resultant from half the population getting pregnant is a gender.
EVERY gender identity is silly. You are only denying my right to have my gender identity because you're a transphobe and a sexist who likes some genders more than others due to familiarity.
