There's no male or female brain, that idea is perpetuated by clickbait leftist news articles and dumb readers who don't read the study.
What they've found is that over a large sample size, a woman/man's brain is more likely to have brain structures that look a certain way, with a huge amount of overlap between the sexes in the middle. What's more, every individual has a different composition of brain structure sizes associated with both sexes. It's impossible for a neuroscientist to look at an individual brain scan and tell if it's the brain of a man or a woman, there's a lot of variation between individuals. Basically people who use this argument are full of shit and don't understand the complexity.
