- There’s a greater argument to be made for binary biological sex, and you can attach obvious descriptions to it to make the two categories distinct. - Gender on the other hand is more fluid (both historically in its expression, and in between cultures). - Biological based terminology can be used historically (e.g. Women’s History)
But this is all off topic, so I’ll stop here.
