Good stuff from Rod Dreher:
Jenner’s heroism, according to the film, consists in his dramatic refusal of Nature — of imposing his own will and desires on nature so profoundly that he repudiates his own nature as a male. Jenner retains his male genitalia, and, of course, maleness in his genes. In other words, everything about Jenner’s material existence (that is, his existence in his body) is male. But Jenner thinks of himself as female, and presents himself publicly as a female. He believes that what he wishes to believe about himself is who he really is, in terms of his gender. And our culture has decided that someone who wishes to assert that he or she is actually of the opposite gender than his or her body, that not only is that person conforming to the Truth — courageously, against the opposition of tradition, religion, society, and so forth — but that courage in part consists of that very willingness to impose one’s will on Nature, to make it serve our desires.
