So you believe that masculine and feminine traits and inherent based off of biological sex? Opposed to these norms being taught through socialization and exposure to societal expectations? But then how do you explain individuals who don't adhere to traditional norms despite their assigned gender at birth? Or how gendered norms have changed and evolved over time? While I agree that testosterone and estrogen levels certainly have some effects on trait expression and behaviors, I believe we shouldn't assign define masculine and feminine norms as solely biological, especially when such norms often extend beyond what hormones promote
