I'm not making assumptions. I'm reporting to you what neuroscientists say. The brain is incredibly plastic and it responds to what it is exposed to. Gender indoctrination begins at birth and is pervasive even when parents attempt to raise children in a "gender neutral" environment. Let me reiterate - what neuroscientists are saying is that we don't know what any biological differences indicate and speculating on that based on entrenched patriarchal narratives is irresponsible and just plain wrong. We do not currently know enough about the brain to be able to make these types of assertions.
