Maybe you've forgotten about adjectives. The use of an adjective to modify a noun does not constitute a denial that the noun is the thing that it is, but rather specifies which type it is.

Hence, if someone writes "trans women", then "trans" is an adjective specifying a distinguishing feature of that category of "woman" much as in "red LEGO", "red" is an adjective describing a distinguishing feature of that "LEGO".

Therefore, if I ask whether the police should have a category of "trans women", it doesn't say that they aren't women. That's not how adjectives work.

The question is just this: which categories should the police keep track of, and why?

Given how many words you spent criticizing a criticism of one position (that you don't even understand, because you don't know what boxes they plan to have on their forms, which is what this was all about), I would have thought that you had a recommendation.
