It's not about being devoid of emotion, it's about not letting it control your actions and decision making when you do have those emotions. Testosterone vs estrogen was an analogy. You are right though, giving into your emotions whether it is a testosterone fueled rage or an estrogen driven meltdown are two sides of the same coin and both genders are capable of both, even at the same time. The worst decisions you will make in your life are the ones where you allow your emotions to drive them. If you disagree with that, fair enough, but good luck with that.
I realize you are hyper focused on the emotion thing, but did you not even bother to read the content? I think we actually agree on that, you know, if you can just take the emotion out of it. If you can do that, I would be interested to hear where you disagree if indeed you do.
