Yes, the reason for the brain differences is entirely cultural because our brains are highly plastic and what they are exposed to determines how they develop. Biological differences around strength have no bearing on much of anything beyond the obvious. We have absolutely no way to determine what any “natural” differences might be because gender indoctrination begins at birth. Of course people should be able to do what they want to do — at least on this, we are agreed.

And you will never hear me say that “men should” or “women must” so don’t even pretend that I did that.
