On the contrary, part of being a well-adjusted person is learning how to express any emotion in a gradual and controlled fashion, without letting it dominate your behavior in dysfunctional ways. As the ancient philosopher Epictetus famously put it: "If anyone were to deliver your body in public to whomever he wished, that any passer-by might do as he liked with it, you would certainly be angry and indignant. But that you should then set your mind at the mercy of all the world, to be troubled and disturbed whenever anyone should happen to revile you--are you not ashamed of that?" In a way, this is at essence the underlying tension that's inherently in play whenever someone advocates for "vulnerability".
