Toxic?
The author says, they don't think all "masculinity" is "toxic." They think that there's a lot of it that harms men because of the restrictions it places on our expression of emotions, especially grief or pain.
That's absolutely true. But the thing I have been thinking lately is, there's nothing we call "masculine", that's both a positive and only masculine. A trait that women just don't manifest. Can you think of one? I'll wait.
