One of the (dumb) arguments against acceptance of transgender people takes disagreement about the definition of “man” and “woman” as dangerous to a functioning society. Setting aside that this argument depends first upon confusion about the difference between gender and biological sex, the idea that we need to agree one this particular ontological fact is very odd when the people making the argument don’t say the same about other ontological (and metaphysical) disagreements.
@arossp Not to mention that even "biological sex" is less a binary thing, as society widely views it, and more of a 2-peak bell-curve with so many asterisks it'll make you see stars.

@OctaviaConAmore @arossp I've seen the bimodal argument before, and I push back a little. That idea still enforces a binary. Imagine the curve in your head, and what is the x-axis? "Maleness"? "Femaleness"? Who determines that?

I know it's a nice visual, but as an intersex and trans person, it's uncomfortable in its inaccuracies. The idea that sex statistically favors two categories is good, but placing those categories on a continuum is not.
