It's a thing called nature
There is such a thing as female nature, and male nature
We are not blank slates unlike what feminists and social constructivists want you to believe - and it sounds crazy to say that, but it really shouldn't
We are defined by our biology first, and while that is somewhat tempered into degrees by society, believing that male and female nature don't exist at all is like claiming sexual reproduction doesn't exist and hasn't evolved for millions of years in all complex life forms
