Yeah righto, cunt. I really don’t think you gotta worry about 99.5% of the population writing in “piss off mate” on their census forms, and as far as the government’s concerned, having accurate demographic data is actually very useful for allocation of funding.

I’m also curious as to what exactly you think the “identity game” you mentioned is.

At any rate, you’re factually incorrect about gender and sex being specific in their definitions. They’re both just bullshit abstract categorisations made according to a vague set of values from across a nebulous grouping of criteria. And unless you arbitrarily mangle their “specific meaning” beyond any utility, neither of them is a simple Male/Female binary in which those categories are mutually exclusive.
