That's a dumb argument. Barring the fact that nobody here is a neurologist, you couldn't sort any sequence into categories if you're not given any information about it.
Imagine if I gave you a string of numbers like 2, 2, 4, 3, 8, 0, 8, 8, 5, 1 and told you to tell me definitively which belong to a data set of frogs and which to a set of cats, and nothing else about the study being conducted. Wow! Would you look at that, there's no difference between frogs and cats.
Or if I showed you a bunch of zoomed-in pictures of eyeballs and demanded to know the race of their owners with no outside information on how you're supposed to tell or what's going on.
Tldr it goes both ways
More information, but this time one study is from 2017. There has ALWAYS been proof that male and female brains express differences.

Meta-analysis reveals a lack of sexual dimorphism in human amygdala volume
The amygdala plays a key role in many affective behaviors and psychiatric disorders that differ between men and women. To test whether human amygdala …
Meta-analysis of matched raw volumes demonstrates a moderate-sized sex difference and average bilateral amygdala volume about 0.3 cm3 (10%) larger in males, comparable to the 11–12% larger overall volume of males’ brains.
•
By contrast, meta-analysis of volumes normalized for overall brain size demonstrated no significant sex difference in amygdala volume.

What's important is grey matter distribution.
On average, males have larger grey matter volume in bilateral amygdalae, hippocampi, anterior parahippocampal gyri, posterior cingulate gyri, precuneus, putamen and temporal poles, areas in the left posterior and anterior cingulate gyri, and areas in the cerebellum bilateral VIIb, VIIIa and Crus I lobes, left VI and right Crus II lobes. Females on average have larger volume at the right frontal pole, inferior and middle frontal gyri, pars triangularis, planum temporale/parietal operculum, anterior cingulate gyrus, insular cortex, and Heschl's gyrus; bilateral thalami and precuneus; the left parahippocampal gyrus and lateral occipital cortex (superior division).
