And you know what else? The crusty, rugged, craggy, weird looking guys don't really show up in Kirby's work until after his return from WW2. This dude spent time in the trenches. He actually killed people, was present at the liberation of a concentration camp. He experienced some trauma, and translated that into the artistic choices that he made. So when Boxer says she can't enter Kirby's world and that it is repulsive, she's right. She can't enter his world because she can't comprehend his trauma.
