I view it not as a denial of difference but outlining that regardless of physiological differences of male and female human bodies, most brains are a composite of traits/features associated with males and females.
"Neuroscientist Daphna Joel and her team examined the brains of 1,400 individuals ... They repeatedly find that some individual, small sections of the brain indeed show patterns that are more typical of males or more typical of females (although millions of sections show no difference at all). However, when they look at all the sections together instead of just a small snapshot, they find only about 3% of people have a brain that is fully “male” or fully “female.” In other words, it is extremely rare to find a consistently pink brain or blue brain. The other 97% of people have brains that are a mosaic of pink and blue. Almost all of us have features common in men and features common in women. Even neuroscientists can’t tell if an individual brain belongs to a man or woman."
If possible, it would have been so interesting to see whether/how cultural conditioning (around gender, etc) affects pattern of brain growth, since such conditioning starts from birth.
