ah yes… ancient and “noble” orders of men often have that symptom of hyper-masculinity. It’s seen with the Night’s Watch in the story of Danny Flint, and it’s seen in the order of knighthood as a whole with Brienne. Women “infiltrating” all-male ranks earns them ire and disrespect.
I would add that the violence that arose in the story of Danny Flint goes beyond that of just a woman joining. It’s the fact that a woman joined *in secret*, that she tricked the men into thinking she was someone she wasn’t, and so when the truth came out, so did the anger at being fooled. It’s a story of men’s bruised pride as much as it is a commentary on how twisted revered orders are beneath the surface.
