Some lines from Margaret Atwood’s novel Life before Man:
Auntie Muriel is unambiguous about most things. Her few moments of hesitation have to do with members of her own family. She isn’t sure where they fit into the Great Chain of Being She’s quite certain of her own place, however. First comes God. Then comes Auntie Muriel and the Queen, with Auntie Muriel having a slight edge. Then come about five members of the Timothy Eaton Memorial Church, which Auntie Muriel attends. After this there is a large gap. Then white, non-Jewish Canadians, Englishmen, and white, non-Jewish Americans, in that order. Then there’s another large gap, followed by all other human beings on a descending scale, graded according to skin color and religion. Then cockroaches, clothes moths, silverfish and germs, which are about the only forms of animal life with which Auntie Muriel has ever had any contact. Then all sexual organs, except those of flowers.
[…]
There are no shades of grey for Auntie Muriel. Her only visible moral dilemma is that she thinks she ought to rank her family with the Timothy Eaton Church members, because of their relation to her; but she feels compelled to place them instead with the cockroaches and silverfish, because of their deplorable behavior.
